python - Django form sporadic validation -

-

i have form accessed class-based generic updateview. validates, among other things, event being updated not on same date another.

the trouble is, when updating fields, e.g. location, changes processed without error being raised, updating others, e.g. name, throws validation errors event date clashing event, errors should occur when location edited.

why editing fields raise validation errors , not editing other fields? validation should check them all.

my view:

class eventeditview(updateview):     template_name = "edit_event.html"     pk_url_kwarg='event_id'     model = event     form_class = eventeditform

which uses form:

class eventeditform(forms.modelform):      class meta:         model = event      def __init__(self, *args, **kwargs):         self.request = kwargs.pop('request', none)         super(eventeditform, self).__init__(*args, **kwargs)       name = forms.charfield(max_length=1024,         initial="give short, descriptive name")     location = forms.charfield(max_length=1024,         initial="be specific, give online map link")     datetimeoptions = {         'format': 'dd/mm/yyyy hh:ii p',         'autoclose': 'true',         'showmeridian': 'true',         }     date = forms.datetimefield(label="date , time",         widget=datetimewidget(options=datetimeoptions,         attrs={'id':"date-time"}))     host_act = forms.charfield(max_length=1024,         initial="what act bring, if any?", required=false)     description = forms.charfield(required=false, max_length=10240)      def clean_location(self):         cd = self.cleaned_data         location = cd.get('location')         if location == "be specific, give online map link" or '':             raise forms.validationerror("please enter location")         return location      def clean_name(self):         cd = self.cleaned_data         name = cd.get('name')         other_names = event.objects.proposed(datetime.now)         if name == "give short, descriptive name" or '':             raise forms.validationerror("please enter name")         return name      def clean(self):         """         check there not event on @         same time , place. check user has not committed         event on same date, somewhere else.         """         cleaned_data = super(eventeditform, self).clean()         event_start_estimate = cleaned_data.get("date") - timedelta(hours=3)         event_end_estimate = event_start_estimate + timedelta(hours=7)         location = cleaned_data.get("location")         events_on_date = event.objects.\             filter(date__range=[event_start_estimate,event_end_estimate])         events_at_location_on_date = events_on_date.filter(location=location)         # check event clash not event clashing         #        events_with_same_date_and_location_id = events_at_location_on_date.values()[0]['id']         #        this_event_id = self.instance.id         try:             if events_with_same_date_and_location_id == this_event_id:                 events_at_location_on_date = false         except:             pass         if events_at_location_on_date:             raise forms.validationerror("there event on \                 date.")         user = self.request         print user         events_on_date_user_has_commit = events_on_date.filter(host__exact=user)         if events_on_date_user_has_commit:             raise forms.validationerror("you committed event\                 on date.")         return cleaned_data

you have few errors in code may or may not related problem.

your if statement in clean_location false because '' false. think want this:

if name in ["give short, descriptive name", '']:

secondly, same thing in clean_name. should be: 

if name in ["give short, descriptive name", '']:

third, in clean, using self.request user object:

user = self.request

should be:

user = self.request.user

maybe these changes fix problem.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
