Using Django Mystery Errors
1

i just wanna have a similar logentry like history in admin page in my own page instead of admin pages. and now it just shows ‘type object ‘object’ has no attribute ‘_meta’’.

view.py

    res = dict()
    res['objects'] = LogEntry.objects.all()  
    LogEntry.objects.log_action(
        user_id=request.user.pk,  
        content_type_id=get_content_type_for_model(object).pk, 
        object_id=object.pk, 
        object_repr=object.__repr__(),
        action_flag=CHANGE,
        change_message=''oooops"
    )
    return render(request, 'homePage.html', {"objects": object})

html

<tbody>
                        {% for i in objects %}
                        <tr>
                            <td>{{ i.action_time }}</td>
                            <td>{{ i.object_repr }}</td>
                            <td>{{ i.object_id }}</td>
                            <td>{{ i.get_action_flag_display }}</td>
                            <td>{{ i.user }}</td>
                            <td>{{ i.change_message }}</td>
                        </tr> {% endfor %}
                    </tbody>

When requesting assistance with an error.

  • Please post the complete error message with the traceback (posted as preformatted text, just like code)
  • Post the complete view and templates involved

You have mismatched quotes here. You have two apostrophes (') at the beginning of oooops instead of a quote character (").

these are the full error message.
and thx for finding bug in change_message .i’ve gotten it right :slight_smile:

This is the summary page shown in the browser. It’s not as complete or as helpful as the traceback provided on the console.

And, we still need to see the complete view and template.

5

and if this error is related to Django version? i searched some tutorials they are using object_repr, but in IDE it just shows no such Unresolved Reference object_repr.

The variable named “object” isn’t defined in this function.

thx a lot. i have known what i need to do.

btw, may i have your idea about how to achieve my purpose about showing the operation history in my own page?

10

You would need to provide specific details about what exactly it is you’re looking to do here.

(Just referring to the “admin’s operation history” doesn’t provide nearly enough information about what you’re looking to show. For example, are you just looking to dump all admin activity? Activity on specific models? Are you looking to track activities performed outside the admin?)

11

yes, i just want to have a form to show all users’ activity like auth change or delete a account with their name, id ,when did this activity.
it’s quite simple to show in admin page, but i got no idea about how to do it in my own page :frowning:

12

The LogHistory model is a model like any other. You would query it and render the results of the query exactly like any other model.
