Hi Guys,
how do i save a backbone model in the database ??
here is how i have tried it and the errors i am getting, please assist ,
/*
*
*
* the field model
*
*
*/
var fieldModel=Backbone.Model.extend({
defaults:{
name:'',
type:'',
placeholder:'',
},
urlRoot:'form',
initialize:function(){
this.on('invalid',function(model,error){
alert(error);
})
},
validate:function(attrs){
if(! $.trim(attrs.name) || ! $.trim(attrs.type)){
return 'Name can not be blank'
}
}
});
/*
*
*
* the collection of fields
*
*
*/
var fieldCollections=Backbone.Collection.extend({
model:fieldModel,
urlRoot:'form',
});
/*
*
*
* The collection of all elements view
*
*
*/
var allFieldsView=Backbone.View.extend({
el:'#designArea',
//template:,
initialize:function(){
this.render();
this.listenTo(this.collection,'add',this.displayOneField)
},
events:{
'click #saveDesignedForm':'saveDesignedForm',
},
render:function(){
this.collection.each(this.displayOneField,this);
return this;
},
// display each field
displayOneField:function(field){
// create a fields view based on each model that is in the
collection
var oneFieldDisplay =new fieldView({model:field});
// append the each models fieldview
// using fieldview created using the model get the el method
this.$el.find('#formDesign').append(oneFieldDisplay.render().el);
},
// save all the models in a collection
saveDesignedForm:function(){
this.collection.each(function(element){
element.save()
})
}
});
the url.py has the following path
url(r'^form-save',saveFormDesign),
from the chrome console i get the following request payload on save
1. {"name":"default name","type":"text","placeholder":"the placeholder
goes here"}
and this is my view
@csrf_exempt
def saveFormDesign(request):
ClientData.objects.create(name='demo',fields=request)
return HttpResponse(request)
here is my stack trace
