            By default plumber is trying to send a valid JSON response. If that's not what you want, change the serialize to something like text and return an empty string

            proxying from containerized production react to containerized flask
            Asked 2021-Jun-15 at 16:20

            I am trying to proxy requests from my containerized React application to my containerized Flask application.

            I was starting the application using npm start (in Docker), and I did not have any issues proxying requests. However, I learned that npm start is not a good way to proceed in production.

            Following the advice here: Run a React App in a Docker Container , I am able to start my containerized production React, but now the requests are not proxied.

            Within the React app, all requests are handled with axios and are formatted: "/api/v1/endpoint". It seems that others have had issues between "http://localhost:80/api/v1/endpoint" and "/api/v1/endpoint". I do not believe this is my issue, unless it arises only in the production environment.

            I have also tried changing my "proxy" address in package.json to the location of the dockerized flask container, and later to the name of the docker container, but I have not been able to make either solution work.

            If anyone can provide guidance on launching a containerized, production React app that proxies requests to a backend container, please advise.

            I am open to using a different server, if the procedures in "Run a React App in a Docker Container" need to be updated.

            I have looked these solutions:

            Answered 2021-Jun-15 at 13:31

            You can use ajax in jquery to easily send and recieve data without page reload and then manipulate the dom using javascript.

            rather than creating a seperate file make a div in index where you want to show the result.

            include jquery before this

            Is it possible to use an Abstract Base Class as a mixin?
            Asked 2021-Jun-15 at 03:43

            TL;DR: Interested in knowing if it's possible to use Abstract Base Classes as a mixin in the way I'd like to, or if my approach is fundamentally misguided.

            I have a Flask project I've been working on. As part of my project, I've implemented a "RememberingDict" class. It's a simple subclass of dict, with a handful of extra features tacked on: it remembers its creation time, it knows how to pickle/save itself to a disk, and it knows how to open/unpickle itself from a disk:



            Answered 2021-Jun-15 at 03:43

            You can get around the problems of subclassing dict by subclassing collections.UserDict instead. As the docs say:

            Class that simulates a dictionary. The instance’s contents are kept in a regular dictionary, which is accessible via the data attribute of UserDict instances. If initialdata is provided, data is initialized with its contents; note that a reference to initialdata will not be kept, allowing it be used for other purposes.

            Essentially, it's a thin regular-class wrapper around a dict. You should be able to use it with multiple inheritance as an abstract base class, as you do with AbstractRememberingDict.

            How to get wtforms to take json and insert data into the form object?
            Asked 2021-Jun-15 at 00:52

            The situation:

            I am using React in the front-end and a Flask api server. I am wanting to send the data from React to the api and once I have done this I would like to use WTForms to run validations on the data before handling it. The question may seem similar to CSRF Protection with Flask/WTForms and React , but this does not answer the question, please take a look through I have put a lot of effort in writing a good question.

            What I have

            Currently the data is being sent successfully as a json object, where the keys match the names within the wtform structure, the aim is to get wtforms to take that json data and insert it into the object and and handle from there as normal

            Install flask

            You can download it from GitHub.
            You can use flask like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
