@login_required decorator only works on first page after login

Using Django Mystery Errors
1

I am trying to use @login_required to only allow login in users to access various views.

My code for the page login directs the user to after logging in is:

@login_required
def wheel(request):
    return render(request, "ISO22301/wheel.html",)

If I the select a link to navigate to another page I get:

Internal Server Error: /ISO22301/introduction/

What is the link that you are selecting?

What is the code for the view of that page? (The view that handles the /ISO22301/introduction/ url?)

3

Here’s the code:

@login_required
def introduction(request):
    create_context=createheader(0) #pass starting values to use to extract desired text, get tuple
    context = create_context[0] #get context to pass 
    return render(request, "ISO22301/introduction.html",context)
4

What is the createheader function?

5

It creates a flexbox graphic that is used by a number of templates. The value passed 0 in this case) Is used to identify which ISO is surveyed:

def createheader(n): # n is the value to use in lists created here, refers to teh ISO being generated

    #Name of browser tab
    browsertab=list(Dashboard.objects.values_list('company', flat=True))
    browsertab=browsertab[n]
        #Name of dashboard
    dashboard_title=list(Dashboard.objects.values_list('dashboard', flat=True))
    dashboard_title=dashboard_title[n]
    # names and text for both ends of LoO to extract value for current project
    project=list(Project.objects.values_list('project', flat=True))
    projecttext=list(Project.objects.values_list('project_text', flat=True))
    outcome=list(Project.objects.values_list('outcome', flat=True))
    outcometext=list(Project.objects.values_list('outcome_text', flat=True))
    # Used to identify specific text for ISO
    project=project[n]
    projecttext=projecttext[n]
    outcome=outcome[n]
    outcometext=outcometext[n]
    #layout data
    areaheader=Area_Header.objects.all() # get names of areas for header
    column_header=Column_Header.objects.all() #headers for table columns
    num_choices=list(Column_Header.objects.values_list('colcount',flat=True)) #h number of unique valoes0 to n
    num_choices_total=num_choices.count(1)
    nchoices = []
    for n in range(num_choices_total):
        nchoices.append(n)
    areatopics = Area_Topic.objects.all() #used in layout to enter topics in flexbox
    areas =  Area.objects.all().prefetch_related('question_set') #Get list of areas tied to question set
    areaheader = Area.objects.values_list('area', flat=True)
    textname= ["Text"] #Comment feild text
    context_header = {
        "textname": textname,
        "area": areas,
        "areatopics": areatopics,
        "areaheader": areaheader,
        "browsertab": browsertab,
        "dashboard_title": dashboard_title,
        "project": project,
        "projecttext": projecttext,
        "outcome": outcome,
        "outcometext": outcometext,
        "nchoices": nchoices,
        "columnheader": column_header,
        }
    return context_header, nchoices

I’m having a hard time reconciling this code with the traceback you’ve posted.

Please post the introduction.html template.

If you’re running this using runserver in a development environment, I suggest deleting all .pyc files that may currently be in your project.

What version of Django are you using?

django==5.1

Template is mostly text placeholders:

 <p>The outcomes of maintaining a BCMS are shaped by the organization’s legal, regulatory, organizational and industry requirements, products and services provided, processes employed, size and structure of the organization, and the requirements of its interested parties.<p>

<p>A BCMS emphasizes the importance of:</p>
    <ul>
    <li>understanding the organization’s needs and the necessity for establishing business continuity policies and objectives;</li>
    <li>operating and maintaining processes, capabilities and response structures for ensuring the organization will survive disruptions;</li>
    <li>monitoring and reviewing the performance and effectiveness of the BCMS; — continual improvement based on qualitative and quantitative measures.</li>
    </ul>
<p>A BCMS, like any other management system, includes the following components:</p>

Is that traceback you posted the complete traceback or is it the second of two consecutive errors with traceback for the same request? (There’s definitely something happening here that isn’t currently being shown, but I don’t know what it might be.)

Ok, now it’s working. I deleted all the @login_required and then reentered them and it works - pages rendered if logged in and return login page if not. PFM…
