從數據庫中預先填充formset_factory來自db

Question

我正在嘗試編制一個應該與現有值一起使用的表單。儘管我預先填充所有字段，但外鍵字段給我一個問題。

這裏是我的forms.py

def make_bowling_form(teamid, fixtureid): 
    class BowlingForm(forms.Form): 
     player = forms.ModelChoiceField(
      queryset=PlayerShortlist.objects.filter(
       team = teamid, 
       fixture = fixtureid 
      ) 
     ) 
     overs = forms.FloatField(initial=0.0) 
     runs = forms.IntegerField(initial=0) 
     wickets = forms.IntegerField(initial=0) 
    return BowlingForm 

和views.py中

@login_required 
def edit_bowling(request, team_id, fixture_id): 
    template = get_template('cricket/edit_bowling.html') 
    if Team.objects.get(id=team_id) == Team.objects.get(owner=request.user): 
     matchscorecard = InningsCard.objects.get(team = team_id, fixture = fixture_id) 
     bowlers = BowlingDetail.objects.filter(innings = matchscorecard) 
     bowlingforms = formset_factory(
      make_bowling_form(team_id, fixture_id), 
      extra=0, 
     ) 
     bowlingforms = bowlingforms(initial = bowlers.values()) 
     page_vars=Context({ 
      'loggedinuser': request.user, 
      'bowlers': bowlers, 
      'bowlingforms': bowlingforms, 
     }) 
    else: 
     error = "You dont have permission to add score for this team" 
     page_vars=Context({ 
      'loggedinuser': request.user, 
      'error': error 
     }) 
    crsfcontext = RequestContext(request, page_vars) 
    output = template.render(crsfcontext) 
    return HttpResponse(output) 

這是給我的所有值正確，除了外鍵字段。牛逼進一步調查我去上打印的bowlers.value（）

[{'runs': 32, 'innings_id': 1, 'wickets': 1, 'player_id': 3, 'overs': 4.0, 'id': 1}, {'runs': 21, 'innings_id': 1, 'wickets': 3, 'player_id': 4, 'overs': 4.0, 'id': 2}, {'runs': 19, 'innings_id': 1, 'wickets': 3, 'player_id': 2, 'overs': 4.0, 'id': 3}] 

和我的模板給我..

<select name="form-0-player" id="id_form-0-player"> 
<option value="" selected="selected">---------</option> 
<option value="37">AC</option> 
<option value="38">AD</option> 
<option value="39">DD</option> 
<option value="40">LF</option> 
<option value="41">22</option> 
<option value="42">dkja</option> 
</select> 

在這種情況下，選擇的值是-------- --- ..它應該是我選擇的價值，但我的bowlers.value沒有給我一個名字..它給了我一個ID。

我該如何糾正這種情況？

使用ModelForm和instance（或queryset爲表單集）：

def make_bowling_form(teamid, fixtureid): 
    class BowlingForm(forms.ModelForm): 
     class Meta: 
      model = Bowling 

     player = forms.ModelChoiceField(
      queryset=PlayerShortlist.objects.filter(
       team = teamid, 
       fixture = fixtureid 
      ) 
     ) 
    return BowlingForm 

和

BowlingFormSet = modelformset_factory(
    make_bowling_form(team_id, fixture_id), 
    extra=0, 
) 
bowlingforms = BowlingFormSet(queryset=bowlers)
