Django-like web framework for go
I am looking for a web framework that has a django-like pattern for go.

Using toggle in for loop
In my Django template, I am retrieving the data from DB and displaying it in table format. Now, when I click on "Name" field, I want to show some data of that person. Initially, while displaying, only the table should be visible, which means the data of the particular person should remain hide and when I click on that person's name, the information about that person should be shown. Now, I have 2 problems. 1st is, when I click on any name, the information about all the persons gets displayed. For example, if there are 3 entries in my DB and if I click on the name of any person than the information about all the 3 people will get displayed. I just want to display the information of the person on which I clicked on. And the second problem is that after clicking on the name, the data is displayed on the top of the table. I want that suppose I am clicking on the second row, then the information should be displayed below the 2nd row and above the 3rd row. <table> <tr> <th>id</th> <th>Name</th> <th>Status</th> </tr> {% for records in obj %} <tr> <td>{{records.id}}</td> <td id="pop">{{records.name}}</td> <div … -

Full config path vs app name in Django INSTALLED_APPS
In the Django documentation, a line reads: New applications should avoid default_app_config. Instead they should require the dotted path to the appropriate AppConfig subclass to be configured explicitly in INSTALLED_APPS. This suggests I should require users of my app (let's called it sports) to use the following string in their INSTALLED_APPS list: "sports.apps.SportsConfig" However, all of the Django apps I use (django-rest-framework, django-cors-headers, django-celery-results) use default_app_config and only require me to specify the first part of the string (in my case "sports"). So how should I write my app? (1) Follow the advice in the docs and force users to write the entire string "sports.apps.SportsConfig" or (2) Follow what all of the other apps in the Django universe are doing and allow users to write only the first part of the string "sports". -
