Exception Type: TemplateSyntaxError at /soukfeed/

Just had the same problem with my app. The following solved it for me:

Because you’re using the {% url %} tag to generate the link to the view, you need to add the URLs for the application to your project’s root URLConf module (via include() calls). If you use the {% url %} tag with a URL name that you haven’t yet set up in your project, it won’t be able to find the correct URL and will simply return an empty string instead of a URL.

So basically the problem is that the url you're looking up must be in the urls.py of your project, otherwise Django can't find and trace it.

It is really not enought information. But the problem is here:

{% url x.content.url_internal_django_link  x.content.id  %}

May be you need that:

{% extends "base.html" %}

{% block content %}    
{% for x in feed %}
    <a href="{{ x.content.get_absolute_url }}">  {{x.content.content}} </a>
    <br/> 
{% endfor %}

{% endblock %}

But I am not sure - it depends from you model code and your general logic

Exception Value: Caught NoReverseMatch while rendering: Reverse for '' with arguments '(1,)' and keyword arguments '{}' not found.

it looks like your x.content.url_internal_django_link is returning an empty string.

Check your db or change your {% url %} tags temporarily to:

{{ x.content.url_internal_django_link }}

to see what is stored and why you are getting empty strings from the db.

I have got the same exception output saying that not able to '(93L,)' and the keyword argument is not found.

Check the urls.py,where you can see that the url is not provided there.So provide the url then youre not going to this error.

Another possibility is that the regex string of URL is not matched with your request.user.username
