We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
login_required decorator is used at the end of the functions.
In the file readthedocs.org/readthedocs/profiles/views.py, `login_required` decorator is used at the end of some functions and for some other functions, it used in the form of `@login_required`, which reduces the readability of the code.

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.

This form class must operate similarly to a standard\n        Django ``ModelForm`` in that it must accept an instance of the\n        object to be edited as the keyword argument ``instance`` to\n        its constructor, and it must implement a method named\n        ``save()`` which will save the updates to the object.\n\n    ``success_url``\n        The URL to redirect to following a successful edit. If not\n        specified, this will default to the URL of\n        :view:`profiles.views.profile_detail` for the profile object\n        being edited.\n\n    ``template_name``\n        The template to use when displaying the profile-editing\n        form. If not specified, this will default to\n        :template:`profiles/edit_profile.html`.\n\n    **Context:**\n\n    ``form``\n        The form for editing the profile.\n\n    ``profile``\n         The user's current profile.\n\n    **Template:**\n\n    ``template_name`` keyword argument or\n    :template:`profiles/edit_profile.html`.\n    \"\"\"\n    profile_obj = request.user.profile\n    if success_url is None:\n        success_url = reverse(\n            'profiles_profile_detail',\n            kwargs={'username': request.user.username})\n    if request.method == 'POST':\n        form = form_class(\n            data=request.POST, files=request.FILES, instance=profile_obj)\n        if form.is_valid():\n            form.save()\n            return HttpResponseRedirect(success_url)\n    else:\n        form = form_class(instance=profile_obj)\n\n    if extra_context is None:\n        extra_context = {}\n    context = {\n        key: value() if callable(value) else value\n        for key, value in extra_context.items()\n    }\n    context.update({\n        'form': form,\n        'profile': profile_obj,\n        'user': profile_obj.user,\n    })\n    return render(request, template_name, context=context)\n\n\n@login_required()\ndef delete_account(request):\n    form = UserDeleteForm()\n    template_name = 'profiles/private/delete_account.html'\n\n    if request.method == 'POST':\n        form = UserDeleteForm(instance=request.user, data=request.POST)\n        if form.is_valid():\n            # Delete the user permanently\n            # It will also delete some projects where the user is the only owner\n            request.user.delete()\n            logout(request)\n            messages.info(request, 'You have successfully deleted your account')\n\n            return redirect('homepage')\n\n    return render(request, template_name, {'form': form})\n\n\ndef profile_detail(\n        request, username, public_profile_field=None,\n        template_name='profiles/public/profile_detail.html',\n        extra_context=None):\n    \"\"\"\n    Detail view of a user's profile.\n\n    If the user does not exists, ``Http404`` will be raised.\n\n    **Required arguments:**\n\n    ``username``\n        The username of the user whose profile is being displayed.\n\n    **Optional arguments:**\n\n    ``extra_context``\n        A dictionary of variables to add to the template context.
