Django request.POST.get未保存到模型字段

我正在尝试保存request.POST字典中的数据。我想从request.POST获取'name'值，该值应与前缀相对应。然而，它不会发生，并且不会将任何内容保存到名称模型中。而且，我没有得到任何错误。你能告诉我怎么解决这个案子吗？多谢各位

视图.py

from django.shortcuts import render
from .forms import modelformset_factory, AssumptionsForm
from .models import Assumptions
from django.core.exceptions import ValidationError
import pdb

model_names = ['A', 'B']

def get_assumptions(request):

    AssumptionFormset = modelformset_factory(
    Assumptions, form=AssumptionsForm, extra=5)

    if request.method == 'POST':



        formsets = [AssumptionFormset(request.POST, prefix=thing) for thing in model_names]

        if all([formset.is_valid() for formset in formsets]):

            for formset in formsets:

                for form in formset:

                    form.save(commit=False)
                    form.Name = request.POST.get('name')
                    form.save()   



    else:

        formsets = [AssumptionFormset(prefix=thing) for thing in model_names]

    return render(request, 'assumptions.html', {'formsets': formsets})

from django import forms
from django.forms import modelformset_factory, ModelForm
from .models import Assumptions

class AssumptionsForm(ModelForm):

    class Meta:
        model = Assumptions
        fields = '__all__'
        exclude = ['Name']

from django.db import models
from django.forms import ModelForm

class Assumptions(models.Model):

    Worst = models.FloatField(null=True, blank=True, default=None)
    Base = models.FloatField(null=True, blank=True, default=None)
    Best = models.FloatField(null=True, blank=True, default=None)
    Name = models.TextField(null=True, blank=True, default=None)

假设.html

<div class="form">
<form action="" method="post">
{% for formset in formsets %} 
    {% csrf_token %}
    {{ formset.management_form }}
    {{ formset.non_form_errors.as_ul }} 
    <h1>{{formset.prefix}}</h1>
    <table id="formset" class="form">
    {% for form in formset.forms %}
    {% if forloop.first %}
    <thead><tr>
        {% for field in form.visible_fields %}
        <th>{{ field.label|capfirst }}</th>
        {% endfor %}
    </tr></thead>
    {% endif %}
    <tr class="{% cycle 'row1' 'row2' %}">
        {% for field in form.visible_fields %}
            <td>
            {# Include the hidden fields in the form #}
            {% if forloop.first %}
            {% for hidden in form.hidden_fields %}
            {{ hidden }}
            {% endfor %}
            {% endif %}
            {{ field.errors.as_ul }}
            {{ field }}
            </td>
        {% endfor %}
    </tr>
    {% endfor %}
    </table>
    <input type="hidden" id={{formset.prefix}} name={{formset.prefix}} />
{% endfor %}    
<input type="submit" value="Submit">
</form>
</div>

您还应该在HTML表单中传递

“name=name”

和

“value={{{formset.prefix}}”

<input type="hidden" id={{formset.prefix}} name="name" value="{{formset.prefix}}" />

---

我明白了。原因是没有创建模型的实例。代码应如下所示：

for form in formset:

    assumption_data = form.save(commit=False)
    assumption_data.Name = request.POST['name']
    assumption_data.save()

其中假设数据是假设模型的一个实例。感谢大家提供的见解。

django post方法获取价值，您可以使用form.Name=request.post['Name']感谢您的见解。我也这么做了，但仍然没有保存到数据库，也没有生成错误。但是当我调试请求时，POST['name']包含'B'。不知道为什么它不保存到数据库中的名称字段。如有其他建议，将不胜感激。谢谢你的真知灼见。我这样做了，但仍然不会保存到数据库，也不会生成错误。然而，当我调试request.POST.get（'name'）时，它包含'B'。不知道为什么它不保存到数据库中的名称字段。如有其他建议，将不胜感激。谢谢。@Martin检查您是否有其他表单错误。是否保存了其他属性？基本、最差和最佳字段中的所有其他输入值都会保存，但此名称属性除外。
