Also, the generated file names will be created with the template name and extension of `*.py`, for example `app/list_pets.py` will be a separate file generated from the jinja template alongside the default `app/main.py` ### Variables You can use the following variables in the jinja2 templates - `imports` all imports statements - `info` all info statements - `operations` `operations` is list of `operation` - `operation.type` HTTP METHOD - `operation.path` Path - `operation.snake_case_path` Snake-cased Path - `operation.response` response object - `operation.function_name` function name is created `operationId` or `METHOD` + `Path` - `operation.snake_case_arguments` Snake-cased function arguments - `operation.security` [Security](https://swagger.io/docs/specification/authentication/) - `operation.summary` a summary - `operation.tags` [Tags](https://swagger.io/docs/specification/grouping-operations-with-tags/) ### default template `main.jinja2` ```jinja2 from __future__ import annotations from fastapi import FastAPI {{imports}} app = FastAPI( {% if info %} {% for key,value in info.items() %} {{ key }} = "{{ value }}", {% endfor %} {% endif %} ) {% for operation in operations %} @app.{{operation.type}}('{{operation.snake_case_path}}', response_model={{operation.response}}) def {{operation.function_name}}({{operation.snake_case_arguments}}) -> {{operation.response}}: {%- if operation.summary %} """ {{ operation.summary }} """ {%- endif %} pass {% endfor %} ``` ### modular template `modular_template/main.jinja2`: ```jinja from __future__ import annotations from fastapi import FastAPI from .routers import {{ routers | join(", ") }} app = FastAPI( {% if info %} {% for key,value in info.items() %} {% set info_value= value.__repr__() %} {{ key }} = {{info_value}}, {% endfor %} {% endif %} ) {% for router in routers -%} app.include_router({{router}}.router) {% endfor -%} @app.get("/") async def root(): return {"message": "Gateway of the App"} ``` `modular_template/routers.jinja2`: ```jinja from __future__ import annotations from fastapi import APIRouter from fastapi import FastAPI from ..dependencies import * router = APIRouter( tags=['{{tag}}'] ) {% for operation in operations %} {% if operation.tags[0] == tag %} @router.{{operation.type}}('{{operation.snake_case_path}}', response_model={{operation.response}} {% if operation.additional_responses %} , responses={ {% for status_code, models in operation.additional_responses.items() %} '{{ status_code }}': { {% for key, model in models.items() %} '{{ key }}': {{ model }}{% if not loop.last %},{% endif %} {% endfor %} }{% if not loop.last %},{% endif %} {% endfor %} } {% endif %} {% if operation.tags%} , tags={{operation.tags}} {% endif %}) def {{operation.function_name}}({{operation.snake_case_arguments}}) -> {{operation.return_type}}: {%- if operation.summary %} """ {{ operation.summary }} """ {%- endif %} pass {% endif %} {% endfor %} ``` `modular_template/dependencies.jinja2`: ```jinja {{imports}} ``` ## Custom Visitors Custom visitors allow you to pass custom variables to your custom templates. E.g. ### custom template `custom-template.jinja2` ```jinja2 #{ % custom_header %} from __future__ import annotations from fastapi import FastAPI ... ``` ### custom visitor `custom-visitor.py` ```python from typing import Dict, Optional from fastapi_code_generator.parser import OpenAPIParser from fastapi_code_generator.visitor import Visitor def custom_visitor(parser: OpenAPIParser, model_path: Path) -> Dict[str, object]: return {'custom_header': 'My header'} visit: Visitor = custom_visitor ``` ### Multiple Files using APIRouter (For Bigger Applications) ``` ├── app # "app" is a Root directory │ ├── main.py # "main" module │ ├── models.py # "models" of the application │ ├── dependencies.py # "dependencies" module, e.g. import app.dependencies │ └── routers # "routers" is a "app subpackage" │ ├── fat_cats.py # "fat_cats" submodule, e.g. import app.routers.fat_cats │ ├── slim_dogs.py # "slim_dogs" submodule, e.g. import app.routers.slim_dogs │ └── wild_boars.py # "wild_boars" submodule, e.g. import app.routers.wild_boars ``` See [documentation](https://fastapi.tiangolo.com/tutorial/bigger-applications/) of APIRouter OpenAPI for more details. **_Generate main aside with all of its routers_**: ```bash $ fastapi-codegen --input swagger.yaml --output app --generate-routers ``` **_Regenerate specific routers_**: ```bash $ fastapi-codegen --input swagger.yaml --output app --generate-routers --specify-tags "Wild Boars, Fat Cats" ```

Also, the generated file names will be created with the template name and extension of `*.py`, for example `app/list_pets.py` will be a separate file generated from the jinja template alongside the default `app/main.py` ### Variables You can use the following variables in the jinja2 templates - `imports` all imports statements - `info` all info statements - `operations` `operations` is list of `operation` - `operation.type` HTTP METHOD - `operation.path` Path - `operation.snake_case_path` Snake-cased Path - `operation.response` response object - `operation.function_name` function name is created `operationId` or `METHOD` + `Path` - `operation.snake_case_arguments` Snake-cased function arguments - `operation.security` [Security](https://swagger.io/docs/specification/authentication/) - `operation.summary` a summary - `operation.tags` [Tags](https://swagger.io/docs/specification/grouping-operations-with-tags/) ### default template `main.jinja2` ```jinja2 from __future__ import annotations from fastapi import FastAPI {{imports}} app = FastAPI( {% if info %} {% for key,value in info.items() %} {{ key }} = "{{ value }}", {% endfor %} {% endif %} ) {% for operation in operations %} @app.{{operation.type}}('{{operation.snake_case_path}}', response_model={{operation.response}}) def {{operation.function_name}}({{operation.snake_case_arguments}}) -> {{operation.response}}: {%- if operation.summary %} """ {{ operation.summary }} """ {%- endif %} pass {% endfor %} ``` ### modular template `modular_template/main.jinja2`: ```jinja from __future__ import annotations from fastapi import FastAPI from .routers import {{ routers | join(", ") }} app = FastAPI( {% if info %} {% for key,value in info.items() %} {% set info_value= value.__repr__() %} {{ key }} = {{info_value}}, {% endfor %} {% endif %} ) {% for router in routers -%} app.include_router({{router}}.router) {% endfor -%} @app.get("/") async def root(): return {"message": "Gateway of the App"} ``` `modular_template/routers.jinja2`: ```jinja from __future__ import annotations from fastapi import APIRouter from fastapi import FastAPI from ..dependencies import * router = APIRouter( tags=['{{tag}}'] ) {% for operation in operations %} {% if operation.tags[0] == tag %} @router.{{operation.type}}('{{operation.snake_case_path}}', response_model={{operation.response}} {% if operation.additional_responses %} , responses={ {% for status_code, models in operation.additional_responses.items() %} '{{ status_code }}': { {% for key, model in models.items() %} '{{ key }}': {{ model }}{% if not loop.last %},{% endif %} {% endfor %} }{% if not loop.last %},{% endif %} {% endfor %} } {% endif %} {% if operation.tags%} , tags={{operation.tags}} {% endif %}) def {{operation.function_name}}({{operation.snake_case_arguments}}) -> {{operation.return_type}}: {%- if operation.summary %} """ {{ operation.summary }} """ {%- endif %} pass {% endif %} {% endfor %} ``` `modular_template/dependencies.jinja2`: ```jinja {{imports}} ``` ## Custom Visitors Custom visitors allow you to pass custom variables to your custom templates. E.g. ### custom template `custom-template.jinja2` ```jinja2 #{ % custom_header %} from __future__ import annotations from fastapi import FastAPI ... ``` ### custom visitor `custom-visitor.py` ```python from typing import Dict, Optional from fastapi_code_generator.parser import OpenAPIParser from fastapi_code_generator.visitor import Visitor def custom_visitor(parser: OpenAPIParser, model_path: Path) -> Dict[str, object]: return {'custom_header': 'My header'} visit: Visitor = custom_visitor ``` ### Multiple Files using APIRouter (For Bigger Applications) ``` ├── app # "app" is a Root directory │ ├── main.py # "main" module │ ├── models.py # "models" of the application │ ├── dependencies.py # "dependencies" module, e.g. import app.dependencies │ └── routers # "routers" is a "app subpackage" │ ├── fat_cats.py # "fat_cats" submodule, e.g. import app.routers.fat_cats │ ├── slim_dogs.py # "slim_dogs" submodule, e.g. import app.routers.slim_dogs │ └── wild_boars.py # "wild_boars" submodule, e.g. import app.routers.wild_boars ``` See [documentation](https://fastapi.tiangolo.com/tutorial/bigger-applications/) of APIRouter OpenAPI for more details. **_Generate main aside with all of its routers_**: ```bash $ fastapi-codegen --input swagger.yaml --output app --generate-routers ``` **_Regenerate specific routers_**: ```bash $ fastapi-codegen --input swagger.yaml --output app --generate-routers --specify-tags "Wild Boars, Fat Cats" ```

Also, the generated file names will be created with the template name and extension of `*.py`, for example `app/list_pets.py` will be a separate file generated from the jinja template alongside the default `app/main.py` ### Variables You can use the following variables in the jinja2 templates - `imports` all imports statements - `info` all info statements - `operations` `operations` is list of `operation` - `operation.type` HTTP METHOD - `operation.path` Path - `operation.snake_case_path` Snake-cased Path - `operation.response` response object - `operation.function_name` function name is created `operationId` or `METHOD` + `Path` - `operation.snake_case_arguments` Snake-cased function arguments - `operation.security` [Security](https://swagger.io/docs/specification/authentication/) - `operation.summary` a summary - `operation.tags` [Tags](https://swagger.io/docs/specification/grouping-operations-with-tags/) ### default template `main.jinja2` ```jinja2 from __future__ import annotations from fastapi import FastAPI {{imports}} app = FastAPI( {% if info %} {% for key,value in info.items() %} {{ key }} = "{{ value }}", {% endfor %} {% endif %} ) {% for operation in operations %} @app.{{operation.type}}('{{operation.snake_case_path}}', response_model={{operation.response}}) def {{operation.function_name}}({{operation.snake_case_arguments}}) -> {{operation.response}}: {%- if operation.summary %} """ {{ operation.summary }} """ {%- endif %} pass {% endfor %} ``` ### modular template `modular_template/main.jinja2`: ```jinja from __future__ import annotations from fastapi import FastAPI from .routers import {{ routers | join(", ") }} app = FastAPI( {% if info %} {% for key,value in info.items() %} {% set info_value= value.__repr__() %} {{ key }} = {{info_value}}, {% endfor %} {% endif %} ) {% for router in routers -%} app.include_router({{router}}.router) {% endfor -%} @app.get("/") async def root(): return {"message": "Gateway of the App"} ``` `modular_template/routers.jinja2`: ```jinja from __future__ import annotations from fastapi import APIRouter from fastapi import FastAPI from ..dependencies import * router = APIRouter( tags=['{{tag}}'] ) {% for operation in operations %} {% if operation.tags[0] == tag %} @router.{{operation.type}}('{{operation.snake_case_path}}', response_model={{operation.response}} {% if operation.additional_responses %} , responses={ {% for status_code, models in operation.additional_responses.items() %} '{{ status_code }}': { {% for key, model in models.items() %} '{{ key }}': {{ model }}{% if not loop.last %},{% endif %} {% endfor %} }{% if not loop.last %},{% endif %} {% endfor %} } {% endif %} {% if operation.tags%} , tags={{operation.tags}} {% endif %}) def {{operation.function_name}}({{operation.snake_case_arguments}}) -> {{operation.return_type}}: {%- if operation.summary %} """ {{ operation.summary }} """ {%- endif %} pass {% endif %} {% endfor %} ``` `modular_template/dependencies.jinja2`: ```jinja {{imports}} ``` ## Custom Visitors Custom visitors allow you to pass custom variables to your custom templates. E.g. ### custom template `custom-template.jinja2` ```jinja2 #{ % custom_header %} from __future__ import annotations from fastapi import FastAPI ... ``` ### custom visitor `custom-visitor.py` ```python from typing import Dict, Optional from fastapi_code_generator.parser import OpenAPIParser from fastapi_code_generator.visitor import Visitor def custom_visitor(parser: OpenAPIParser, model_path: Path) -> Dict[str, object]: return {'custom_header': 'My header'} visit: Visitor = custom_visitor ``` ### Multiple Files using APIRouter (For Bigger Applications) ``` ├── app # "app" is a Root directory │ ├── main.py # "main" module │ ├── models.py # "models" of the application │ ├── dependencies.py # "dependencies" module, e.g. import app.dependencies │ └── routers # "routers" is a "app subpackage" │ ├── fat_cats.py # "fat_cats" submodule, e.g. import app.routers.fat_cats │ ├── slim_dogs.py # "slim_dogs" submodule, e.g. import app.routers.slim_dogs │ └── wild_boars.py # "wild_boars" submodule, e.g. import app.routers.wild_boars ``` See [documentation](https://fastapi.tiangolo.com/tutorial/bigger-applications/) of APIRouter OpenAPI for more details. **_Generate main aside with all of its routers_**: ```bash $ fastapi-codegen --input swagger.yaml --output app --generate-routers ``` **_Regenerate specific routers_**: ```bash $ fastapi-codegen --input swagger.yaml --output app --generate-routers --specify-tags "Wild Boars, Fat Cats" ```
