Coercing to Unicode: need string or buffer, function found on Django form

I'm new on Django and I'm making a formwhen I press submit I'm getting this error that I haven't seen before: TypeError at /catalog/ coercing to Unicode: need string or buffer, function found

My forms.py looks like:

class AppsForm(forms.Form):
    def __init__(self, *args, **kwargs):
        policiesList = kwargs.pop('policiesList', None)
        applicationList = kwargs.pop('applicationList', None)
        super(AppsForm, self).__init__(*args, **kwargs)
        if policiesList and applicationList:
            self.fields['appsPolicyId'] = forms.ChoiceField(label='Application Policy', choices=policiesList)
            self.fields['appsId'] = forms.ChoiceField(label='Application', choices=applicationList)
        else:
            self.fields['appsPolicyId'] = forms.ChoiceField(label='Application Policy',
                                                                  choices=('No application policies found',
                                                                           'No application policies found'))
            self.fields['appsId'] = forms.ChoiceField(label='Application', choices=('No applications found',
                                                                    'No applications found'))

My views.py looks like:

def main(request):
    if validateToken(request):
        appList = getDetailsApplications(request)
        polList = getDetailsApplicationPolicies(request)
        message = None
        if request.method == 'POST' and 'deployButton' in request.POST:
            form = AppsForm(request.POST, policiesList=polList, applicationList=appList)
            if form.is_valid():
                deploy(request, form)
            else:
                form = AppsForm(policiesList=polList, applicationList=appList)
                message = 'Form not valid, please try again.'
        elif request.method == 'POST' and 'undeployButton' in request.POST:
            form = AppsForm(request.POST, policiesList=polList, applicationList=appList)
            if form.is_valid():
                undeploy(request, form)
            else:
                form = AppsForm(policiesList=polList, applicationList=appList)
                message = 'Form not valid, please try again.'
        else:
            form = AppsForm(policiesList=polList, applicationList=appList)
        return render_to_response('catalog/catalog.html', {'message': message, 'form': form},
                          context_instance=RequestContext(request))
    else:
        return render_to_response('menu/access_error.html')

The error happens on deploy(request, form) and undeploy(request, form), they are on another app and I import both from the app/views.py.

Here I show one of them because I think the problem on both it's the same, but I'm not unable to fix it...

def deploy(request, form):
    if validateToken(request):
        policy = form.cleaned_data['appsPolicyId']
        applicationID = form.cleaned_data['appsId']
        headers = {'Content-Type': 'application/json'}
        deployApp = apacheStratosAPI + applications + '/' + applicationID + '/' + deploy + '/' + policy
        req = requests.post(deployApp, headers=headers, auth=HTTPBasicAuth(request.session['stratosUser'],
                                                                      request.session['stratosPass']),
                       verify=False)
        if req.status_code == 202:
            serverInfo = json.loads(req.content)
            message = '(Code: ' + str(req.status_code) + ') ' + serverInfo['message'] + '.'
            return render_to_response('catalog/catalog.html', {'message': message, 'form': form},
                  context_instance=RequestContext(request))
        elif req.status_code == 400 or req.status_code == 409 or req.status_code == 500:
            serverInfo = json.loads(req.content)
            message = '(Error: ' + str(req.status_code) + ') ' + serverInfo['message'] + '.'
        return render_to_response('catalog/catalog.html', {'message': message, 'form': form},
                  context_instance=RequestContext(request))
    else:
        return render_to_response('menu/access_error.html')

The error it's on the line:

deployApp = apacheStratosAPI + applications + '/' + applicationID + '/' + deploy + '/' + policy

When I debug, I see that the variables are correct and on format u'value'. I don't know why now I'm getting the Unicode error because on other forms that I have the values are on this format and I don't get any error.

Why I get this error now? Thanks and regards.

One of the things you're including in that string concatenation is deploy. Since that isn't defined within the current scope, Python will look for the nearest declaration of that name, which is the current function itself, hence the error.

I don't know where that name is actually supposed to be defined, but you should probably do it within your function; and, in any case, you will need to rename either the variable or the function.
