[google-appengine] Fill a Form on the same page with different classes - write to DB and display values
I have a model with 5 entities and intend to create a form (on the
same page) but do not know how to integrate more than one form.
In my main, i can play very well with the forms and write to database,
but I need to put more fields on the page.
These fields are of different models.
My models:
Teacher, Account(ReferenceProperty), Experience (ReferenceProperty),
ServiceDistribution(ReferenceProperty), Experience(ReferenceProperty)
My forms:
class TeacherForm(djangoforms.ModelForm):
class Meta:
model =models.Teacher
exclude = ['user']
and the same for other models
My Main:
class CreateCvHandler(webapp.RequestHandler):
def post(self):
if self.request.get('EscTeacher'):
id = int(self.request.get('EscTeacher'))
teacher=models.teacher.get(db.Key.from_path('Teacher',
id))
else:
teacher= models.teacher()
data = forms.TeacherForm(data = self.request.POST)
if data.is_valid():
userList= models.Account.all()
userList.filter('user =', users.get_current_user())
for user in userList:
teacher.user=user.key()
teacher.unity=self.request.get('unity')
teacher.category=self.request.get('category')
teacher.regime=self.request.get('regime')
teacher.put()
docExp.put()
self.redirect('/academy')
else:
self.redirect('/createCv')

[google-appengine] Re: Fill a Form on the same page with different classes - write to DB and display values
I apologize if I was not specific. My program will help teachers meet
their curriculum vitae. The sheet will be printed in pdf format. This
single sheet has several forms that are of different classes. So far
only seen examples of forms with only one class and I'm having trouble
getting the form with more than one class, write on DB and display the
data.
In my particular case, the sheet with the forms would have five
classes.

[google-appengine] Re: Fill a Form on the same page with different classes - write to DB and display values
Sorry, but I did not understand. I got the forms (db.Model), in the
example i´ve included only the class Teacher and the respective form.
But i have 5 more models/classes/forms
My code is fine with just one model/form.
My question is how to integrate into my main, forms of different
classes.
Do I have teacher.put (), Experience.put (), and so on?
or is there other way?
If someone showed me a real example of implementation, i would
appreciate.

[google-appengine] Re: Fill a Form on the same page with different classes - write to DB and display values
Hello everyone. I have this code that works. My class is a db.Model
one2many with a teacher, experience, and so on...
What I want is to call the class teacher with forms, but also intend
to include other classes, like a form from experience class and a form
from category. These classes are as foreign Key teacher.
I wonder how to derive classes for teachers
This is my main:
class CreateCvHandler(webapp.RequestHandler): def post(self): if
self.request.get('EscTeacher'): id =
int(self.request.get('EscTeacher'))
teacher=models.teacher.get(db.Key.from_path('Teacher', id)) else:
teacher= models.teacher() data = forms.TeacherForm(data =
self.request.POST) if data.is_valid(): userList= models.Account.all()
userList.filter('user =', users.get_current_user()) for user in
userList: teacher.user=user.key()
teacher.unity=self.request.get('unity')
teacher.category=self.request.get('category')
teacher.regime=self.request.get('regime') teacher.put()
self.redirect('/academy') else: self.redirect('/createCv'
Can anyone send me a snippet
Thanks

[google-appengine] Appengine - Reportlab (Get Photo from Model)
Hi, I´m using the latest reportlab version 2.5 to generate PDF´s.
I´m also using Google App Engine and Django.
I can get also an image that is in my source folder. Ex: for heading
or footer.
Everything went well to generate the PDF, but I'm having great
difficulty printing to a PDF an image that an user uploaded, like his
own photo.
The photo is a property and is defined in model as BlobProperty ().
Handler:
class savePDF(webapp.RequestHandler):
def post(self):
user= models.Users.all()
p = canvas.Canvas(self.response.out)
p.drawString(50, 720, 'Curriculum Vitae : '+ '%s' %
user.name)
image = canvas.ImageReader(StringIO.StringIO(user.photo))
p.drawImage(image, 40,700)
Model:
class User(db.Model):
photo = db.BlobProperty()
name = db.StringProperty(required = True)
View:
Upload Photo:
User Name:
{{ user.name }}
User Photo:
{{ user.photo }}
Note: I´ve modified utils.py this post.
I´m getting errors like this one:
File "C:\Users\hp\workspace\x-ray\src\principal.py", line 441, in post
image = canvas.ImageReader(StringIO.StringIO(user.photo)) File
"reportlab.zip\reportlab\lib\utils.py", line 588, in init File
"reportlab.zip\reportlab\lib\utils.py", line 582, in init
RuntimeError: Imaging Library not available, unable to import bitmaps
only jpegs fileName=
identity=[imagerea...@0x4a62290].
Please note that i uploaded an .jpeg image.
So, i don´t get the error. If someone could help, i´d be very happy.
The problem that i´m facing right now is when a user upload a photo,
isn´t displayed on his PDF.
I´ll show you a short pic tinypic.com/r/2ngeont/7, but the image shown
is uploaded by me not by the user.
