Django将文件从一个视图动作传递到另一个

Question

I have a view with two actions. First one renders FileInput for csv. After submit, I read csv header and render the template for second action with dropdown containing header items. After dropdown items are selected and submitted, I want to read csv file, saving selected columns to db in second action. How can I pass file from one action to another?

Answer 1

Short answer: you can't. The solution here is to store the file somewhere and save the file path in session, then read the path back from session and re-read the file.

Also, having the same view doing so many things is possibly not the best design, but YMMV...

Answer 2

腌制该文件并在视图中的会话中存储腌制详细信息，并在另一个视图中从会话中访问腌制详细信息。
