flask-xxl - 构建大型网络应用, 来令 flask 感觉象 Django

jopen 10年前

以最佳实践的形式来指引如何构建大型网络应用, 来让 flask 感觉象 Django.

What this provides:

basemodels.py
- with a BaseMixin class that provides many useful CRUD operations, IE: model.save(), model.delete()
baseviews.py
- with a BaseView class that is subclassed from Flask.views.MethodView to allow easy definition of view responses to get and post requests.
- BaseView also has many builtin helpers/imports to speed development, ie:
  - BaseView.render() calls render_template(BaseView._template,**BaseView._context) easily define either or both in the class variable section of the class and then add,change/ w/e based on logic that happens during request processing. example:
```
class ExampleView(BaseView):      _context = {          'some_flag':True,      }        def get(self,new_flag=False):          if new_flag:              self._context['new_flag'] = new_flag              self._context['some_flag'] = False          return self.render()
```
  - BaseView.redirect(endpoint) is a reimplementation of flask.helpers.redirect which allows you to directly enter the endpoint, so you dont have to run it through url_for() first.
  - ```
  BaseView.get_env()
```
  returns the current jinja2_env
- ```
BaseView.form_validated()
```
    returns true if all forms validate
  - namespaces imported into BaseView: BaseView.flash == flask.flash
