sir yha mujhe ek cheez ko samajhne mai problem aati hai , sor jese maine line1 mai
form=forms.loginform -> isse form variable mai form store ho gya
and line_2 mai hum request type dekh rhe hai GET ya POST
par sir jab hum HTML file kai andar jaate hai vha hum form bharte hai and submit krte hai tab vo request POST type ki banti hai

par iss code mai humne pehle form bnaya (line 1 mai ) phir hum request type check kar rhe hai , par jab abhi user ne form bhara hi nahi to hum abhi request type kyu check kr rhe hai

line 10 mai hum form bhej rhe hai html file mai
and then vo html file render hogi and then hum form bharege phir submit ab reuest POST type ki hui.
sir mujhe ye flow samjh nahi aa rha kese ho rha hai , hum line 2 mai request.method check kr rhe hai iska matlab use rne form bhar diya hai
par form to humne user ko line 11 mai bheja hai using dictionary .

PLXX SIR REPLY FAST .

sir , ye get_likes and get_comments models.py mai use krna to samajh aa gya, par sir mai sooch rha tha agar hum views.py mai ise code kre or vha se le to kese krege .
mera matlab , views.py mai ek function hai HOME_PAGE vo dictionary mai pass krde likes and comments ka count for every socialIssue created and use hum HTML mai use kr lege using jinja tags -> {{likes}} {{comments}}.

bina related_name kai use kre -> _set.count() ye method hota haina , sir maine try kiya tha

issue=models.SocialIssue.objects.get(id=1)
like=issue.socialissuelikes_set.count()
comment=issue.socialissuelikes.set_count()

par ye error de rha hai , or uppar se iss traah se hum , one by one manually karna padega , runtime pe konsa issue khola kisne khola to ye chalega nahi ( ye vese bhi nahi chal rha ).

sir mai ye pooch rha hu hum get_likes and get_comments ye function , hum views.py se kese lege
