使用Django模板表單+表單嚮導+脆皮 - 不進行到第二步

我對django中的表單相當陌生。使用Django模板表單+表單嚮導+脆皮 - 不進行到第二步

我的問題是我有幾個非常大的模型，我必須分解成一系列更小的表單供用戶填寫。

因此，我一直在玩弄香脆的表單，昨天在YouTube上觀看Mike Hibberts教程（Python Django教程19 - 使用表單嚮導）後，我想看看我是否可以用脆皮形式進行這項工作。

一切似乎呈現OK給我，但是當我按下提交表單似乎被驗證，但不會繼續執行步驟2

我這樣做完全錯了？

感謝您的任何幫助或建議！

我想我已經解決了一點問題，或者只是運氣好。

在forms.py其中所述元（）字段=「__所有__」

需要被改變以反映感興趣的領域，我使用的可變Sheet1_layout和Sheet2_layout。之後，嚮導似乎繼續下一步。

forms.py

from django import forms 
from crispy_forms.helper import FormHelper 
from crispy_forms.layout import Submit, Layout, ButtonHolder 
from crispy_forms.bootstrap import StrictButton 

from models import ProcessSheet 

Sheet1_layout = (
    'sheet_id', 
    'sheet_title', 
    'part_name', 
    )   
class Sheet1(forms.ModelForm): 

    def __init__(self, *args, **kwargs): 

     print "sheet 1 init!!!!!!!!!!!!!!!" 
     super(Sheet1, self).__init__(*args, **kwargs) 
     # If you pass FormHelper constructor a form instance 
     # It builds a default layout with all its fields 
     self.helper = FormHelper(self) 
     self.helper.form_tag = False 
     self.helper.form_class = 'form-horizontal' 
     self.helper.label_class = 'text-center col-lg-4' 
     self.helper.field_class = 'col-lg-8' 

     self.helper.layout = Layout(Sheet1_layout, 
            ButtonHolder('save', css_class='btn-warning'), 
            ) 
     self.helper.layout.append(Submit('save', 'Save')) 
    class Meta: 
     model = ProcessSheet 
     fields = Sheet1_layout 


Sheet2_layout = (
    'cooling', 
    'nozzle', 
    'zone_5', 
    )   
class Sheet2(forms.ModelForm): 

    def __init__(self, *args, **kwargs): 
     super(Sheet2, self).__init__(*args, **kwargs) 
     # If you pass FormHelper constructor a form instance 
     # It builds a default layout with all its fields 
     self.helper = FormHelper(self) 
     self.helper.form_tag = False 
     self.helper.form_class = 'form-horizontal' 
     self.helper.label_class = 'text-center col-lg-4' 
     self.helper.field_class = 'col-lg-8' 

     self.helper.layout = Layout(Sheet2_layout, 
            ButtonHolder('finish', css_class='btn-warning'), 
            ) 
     self.helper.layout.append(Submit('save', 'Finish')) 
    class Meta: 
     model = ProcessSheet 
     fields = Sheet2_layout 

class TestSheet1(forms.Form): 
    sheet_id = forms.CharField(max_length=16) 

class TestSheet2(forms.Form): 
    hello = forms.CharField(max_length=16)

爲了在以後任何人，我認爲香港專業教育學院解決了我的問題。花了一點時間讓我弄清楚，但我堅持不懈的修補工作得到了回報。對不起，我沒有詳細介紹我必須改變的內容，但我確定你們大多數人可以看到我發佈的代碼發生的變化。形式看起來很棒！會話嚮導按預期工作！似乎都好。祝大家好運！

還沒完全實現完整的實現，但我以此爲例。我會評論我在答案中找到的內容。謝謝你寫這個。 – Axwack 2016-06-21 17:34:44

你有沒有改變任何表2或你是否只是使用表1作爲例子？ TestSheet1和TestSheet2發生了什麼？是否因爲你有你的ModelForm？ – Axwack 2016-06-21 18:27:39

拿走了你的代碼，但按鈕不是動態的，但你讓它們變成靜態的。有理由嗎？ – Axwack 2016-06-22 19:28:13
