In the categories route, you render a categories.html template, which will also be inside a posts directory inside the templates folder.To solve this problem, either stop the server that’s currently running via CTRL+C, then run flask run again, or if you want to run both applications at the same time, you can pass a different port number to the -p argument, for example, to run another application on port 5001 use the following command: We developed a custom web application on top of the Salesforce platform and distributed it in the AppExchange store. Next, create a new categories.html file inside the posts directory.

Next, map out the working directory and set the PATH environmental variable so that the init system knows that the executables for the process are located within our virtual environment. Also specify the command to start the service. This command will do the following: You use a class called Config and set configuration values using class variables. Here, you set three configurations:You handle POST requests inside the if request.method == 'POST' condition. You extract the title and content the user submits from the request.form object. If the title is empty, you use the flash() function to flash the message Title is required!. You do the same in case of empty content.
