python - Create a MultipleChoiceField using rows from another model, -

i creating online job application company multiple locations. allow applicant able select checkboxes represent every store apply (could multiple). hesitant hard code these scalability purposes, had hoped create 2 models (i have more that, example these 2 relevant):

applicant

class applicant(models.model):     name = models.charfield(max_length=200)     city = models.charfield(max_length=200)     state = models.charfield(max_length=200)     zip = models.charfield(max_length=200)     social_security_number = models.charfield(max_length=200)     phone = models.charfield(max_length=200)     alt_phone = models.charfield(max_length=200, blank=true)     us_citizen = models.booleanfield()     committed_felony = models.booleanfield()     is_16 = models.booleanfield()     has_drivers_license = models.booleanfield()     is_disabled = models.booleanfield()     prev_employed = models.booleanfield()     felony_explanation = models.textfield(blank=true)     disabled_explanation = models.textfield(blank=true)     prev_employment_manager = models.charfield(max_length=200, blank=true)     prev_employment_year = models.charfield(max_length=4, blank=true)     skills = models.textfield()     was_completed = models.booleanfield(default=false)      def __unicode__(self):         return self.name 

store

class store(models.model):     code = models.charfield(max_length=10)     description = models.charfield(max_length=200)     city = models.charfield(max_length=20)     state = models.charfield(max_length=20)      def __unicode__(self):         return self.description 

i (i think) add multiplechoicefield in applicant model, creates choices of instances of store (one each row). far, have tried in applicant class:

def get_stores():         self.stores = store.objects.all() 

but unable (as far can tell) grab instances of store had hoped. here few questions have:

• is possible reference model that?
• is referencing store model applicant model right beginning creating several checkboxes let applicant select of stores applying (and allow list change dynamically)?
• is multipleselectfield best way once have pulled of store instances?

this seems canonical use case manytomanyfield.

class store(models.model):     ...  class applicant(models.model):     name = models.charfield(max_length=200)     ...     was_completed = models.booleanfield(default=false)      stores = manytomanyfield(store, related_name='applicants') 

when display form in field, should automatically use multipleselectfield
