![]() ![]() In the Django Models we just need to define the type of variables and their disposition in the form (in ModelAdmin) to generate a HTML form for data edition.įor the GUIs that I wanted to build in my python scripts, I would like to have the same simplicity, so I could focus on the algorithms and not on GUIs developing. That was the idea.Īfter looking into the several python options for GUI interfaces, PyQt was the one that seemed the best tool for a fast development with the QtDesigner, but after a while developing in Qt, switching between the designer and the python IDE was becoming too costly in terms of time because the interfaces were constantly evolving.īeing a Django developer, I did get inspiration on it for this framework. With GUI applications, users would be able to set the parameters using a GUI interface and visualize the results instantly without the need of restarting the script. To test each set of parameters the script had to be executed. ![]() The idea was to transform scripts which had already been developed into GUI applications with a low effort and in a short time.įor example in my computer vision applications in the majority of the times there were variables that had to be set manually in the scripts for each video, to adjust the thresholds, blobs sizes, and other parameters to the environment light conditions. The development of this library started with the necessity of allowing users with low programming skills to edit parameters from my python scripts. Due to its simplicity it has a low learning curve.Įxamples of applications developed in Pyforms GUIĬheck the documentation at and Rationale behind the framework.Turn the prototyping much easier and fast.It makes the applications maintenance easier.The code is organized in modules and prepared to be reused by other applications.It is designed to allow the coding of advanced functionalities with a minimal effort.Avoid the constant switching between the GUI designers and the Python IDE.With a minimal API, interfaces are easily defined using a short Python code.The library provides an API in Python to develop applications that can be executed in Windows GUI mode, Web mode, or in Terminal mode. Now that we’ve verified that we’re able to print the values of our inputs, we can then write additional code to process them - do more processing, add them into some database, or whatever you wish to do with your inputs.Pyforms is a Python 3 cross-enviroment framework that aims the boost the development productivity. Check the terminal you used to run your Python Flask application - the name and email you entered into your form should be printed there. Try entering a name and an email into your form, then click on the submit button. request.form returns whatever we enter into the name input field, and request.form returns whatever we enter into the email input field. We have 2 input fields, 1 with the name name and another with the name email. You can think of request.form as a dictionary containing a bunch of key-value pairs, keys being the name attributes in our input fields, and the values being the values of the input fields (essentially what we enter into the input fields). This if runs when we make a POST request to our Python Flask backend, which happens when we click on the submit button. ![]() Next, let’s add an if statement if thod = "POST". The methods= keyword argument allows our home function to process both GET and POST requests. When we click on the submit button in our form, it makes a POST request to our Python Flask backend. Linking This To Python Flask methods=)įirst, remember to add methods= to our app.route decorator. However, this won’t have any real functionality yet. If we add these, we’ll be able to see the newly added input fields when we visit our / endpoint. Add name attributes to our input fields - these name attributes will be how Python Flask identifies our input fields.This is what our webpage should roughly look like: Here, we wish to add input fields into our HTML file, home.html, in order to ask our user for a name and an email. ![]() Note: remember to put home.html in a folder templates Adding Inputs To Our HTML File Let’s Start With A Basic Flask App app.py from flask import * This article attempts to display as simply as possible how we can create a form in Python flask asking for a name and an email, and how this form data can be passed back to our Python code. Python Flask is probably one of the simplest frameworks for Python beginners to get into web development. ![]()
