Serializer 1.1 Data Validation When deserializing data, the validity of the data needs to be checked. At this point you can call is_valid() for validation, and if a validation error occurs, you can get the error message from the .errors attribute. For example: 1 2 3 4 serializer.is_valid() # False serializer.微信公众号DjangoPythonAPIInterfaceR&Dhttps://www.chenshaowen.com/en/blog/viewset-and-serializer-in-rest-framework.htmlSun, 18 Nov 2018 00:00:00 +0000Sun, 18 Nov 2018 00:00:00 +0000https://www.chenshaowen.com/en/blog/viewset-and-serializer-in-rest-framework.html1. View Class in Django First, recall how Django handles a request. After receiving a request, Django creates a handler of type WSGIHandler, and the handler controls the entire processing flow. So how are the request URL and the View associated with each other? Django first loads the URLconf according to the ROOT_URLCONF setting, then matches the URLpatterns in the URLconf one by one in order, stopping as soon as a match is found.微信公众号DjangoPythonAPIFrameworkInterfaceR&Dhttps://www.chenshaowen.com/en/blog/using-axios-in-vue.htmlMon, 25 Jun 2018 15:00:00 +0000Mon, 25 Jun 2018 15:00:00 +0000https://www.chenshaowen.com/en/blog/using-axios-in-vue.html1.

To lower communication costs and prevent possible security risks, and following the principle of convention over configuration, it is necessary to standardize the API specification.

Many SaaS applications have agreed-upon error codes, some used to handle login state, others to mark business logic status.

Basic Concepts 1.1 Ajax Ajax stands for “Asynchronous JavaScript and XML”. At its core it is made up of the JavaScript, XmlHttpRequest, and DOM objects: through the XmlHttpRequest object it sends an asynchronous request to the server, gets data back from the server, and then uses JavaScript to manipulate微信公众号FrontendToolsAxiosAjaxAPIhttps://www.chenshaowen.com/en/blog/permissions-of-django-rest-framework.htmlFri, 07 Jul 2017 06:47:19 +0000Fri, 07 Jul 2017 06:47:19 +0000https://www.chenshaowen.com/en/blog/permissions-of-django-rest-framework.html1. Permission Management in DRF Permission management in Django REST Framework consists of two parts. One is Authentication. It specifies how the user is authenticated, obtaining request.user. The other is Permissions. It performs permission control over Django resources and user categories. 1.1 Authentication Methods The relevant source is in the rest_framework/authentication.微信公众号DjangoPythonBackendSecurityAPIPermissionsR&Dhttps://www.chenshaowen.com/en/blog/101-of-django-rest-framework.htmlThu, 22 Jun 2017 23:50:15 +0000Thu, 22 Jun 2017 23:50:15 +0000https://www.chenshaowen.com/en/blog/101-of-django-rest-framework.htmlIn the SaaS development I work on, there is a fairly high demand for development efficiency.

When third-party interfaces are involved, API and documentation changes can be even faster in multi-party collaboration scenarios. To make maintaining the API and handing over documentation easier, here is a documentation generation tool worth recommending — apidoc. 1.
