how to utilise a form template in an admin template

Finally!! I figured it out!!

So the error was with the admin view in app.py. My code originally was as follows:

@app.route('/admin')
@login_required
def admin():
    if (models.User.is_admin == True):
        return render_template('admin.html')
    else:
        return redirect(url_for('index'))

After much naval gazing, pulling one's hair out, I figured out that when you inherit template views, any forms need to also be declared in the top level view. So for example, my admin.html was looking for a form from standards.html. But I needed to include the form declaration in the admin view function. So my code now looks as follows:

@app.route('/admin')
@login_required
def admin():
    form = forms.StandardForm()
    if (models.User.is_admin == True):
        return render_template('admin.html', form=form)
    else:
        return redirect(url_for('index'))

With the addition of:

form = forms.StandardForm()

and

, form=form

It worked as expected. I tried it with and without one or other bits of the above code and it won't work unless both are present.

Thanks for the support Jeff Muday & jb30. Man that was a tough one!! :)

If you are using the Treehouse Workspaces, it has a rather old version of Flask-WTF installed (version 0.10.3). Unfortunately, a user can't upgrade Flask-WTF.

No worries-- you can change your import from FlaskForm to just Form, or you could alias it like I show below.

from flask_wtf import Form as FlaskForm

I hope this helps.

So I've still not been able to fix this yet, which does not bode well for my coding skills. I am simply trying to take what I'm learning on the course and extend it for practice and proof I can walk on my own two feet. So, I could really use a helping hand.

In Kenneth's social app, there is a part where we check to see if the user is an admin. If they are, I have it redirecting to a basic admin page. Nothing special here, it's just a template.

But, in most admin systems, you get a dashboard and quick reference tasks that can be performed. This is what I am trying to play around with.

So in my admin.html template, I would like to show another template that allows an admin to add something to a database. For the sake of my example, I have called it standards.html, which contains a two field form. On the admin page, I would just like to show this standards form so that the admin can enter something.

The error I am getting is:

werkzeug.routing.BuildError: Could not build url for endpoint 'standards'. Did you mean 'set_standard' instead?

Now I'm thinking that this means, from my 'admin.html' code below...

{% extends 'layout.html' %} {% from 'macros.html' import render_field %} {% block content %}
<h1>Welcome to the admin page!</h1>
{{ url_for('standards') }}{% endblock content %}

...it doesn't know how to find or render the 'standards.html' file. I'm guessing that I'm either missing something in my code or I am using the wrong code to try and write in the standards file.

I have tried using:

{{ render_template('standards.html') }}

But then the error is 'render_template is not defined'.

I'm not necessarily after the answer, just a point in the right direction. It's making me feel pretty rubbish on what seems like it should be a simple problem.

Thanks in advance.

The Werkzeug error message is telling you to direct the actual Python name for the function in the code url_for("set_standard")

This is handy, because you could refactor your program and not have to change the template as long as your name for the routing function was still set_standard

You could also route "old school style" with a hardcoded URL as I show in the alternate route

Say your app had code like below...

@app.route('/standards')
def set_standard():
    # code
    # omitted
    # for clarity
     return render_template('standards.html', form=form)

Then your template would look something like this-- Extra HTML is added to make the links clickable, and stand these out in their own <div> block.

{% extends 'layout.html' %}
{% from 'macros.html' import render_field %}

{% block content %}

<h1>Welcome to the admin page!</h1>
<div>
    <a href="{{ url_for('set_standard') }}">Standards page</a>
</div>

<h2>Alternate routing "old school"</h2>
<div>
    <a href="/standards">Standards page</a>
</div>

{% endblock content %}

Good luck with Python and Flask-- I have learned so much, and use Python frameworks all the time on my job!

@AndyHughes If you have set it up in a TreeHouse workspace, you can post it as a Snapshot by clicking on the "suitcase" icon in the upper right-hand area of the workspace. Then post the link back to this thread.

I would be happy to take a look at it for you.

It is probably something simple that is holding you up.
