Question

我想将数据填充到数据库中并输出。但我不知道哪里出错了，因为我的数据根本没有保存到数据库中。在views.py中，奖学金只是一个奖学金对象，LS奖学金显示奖学金中的所有数据。我有其他模型和视图的类似代码，但我不知道我在这里做错了什么，使得数据无法保存到数据库中。任何人都可以建议我在哪里错了

您正在使用两个视图来呈现单个模板。

您可以将视图合并为一个视图，也可以减少逻辑。如果我已正确理解您的问题，您可以使用更多这样的视图，

def scholarship(request, id=None):
    query_results = []
    if request.method == "POST":
        form = ScholarshipForm(request.POST)
        if form.is_valid():
            scholarship = form.save(commit=False)
            scholarship.save()
    else:
        form = ScholarshipForm()
        id = request.GET.get('scholarship')
        query_results = Scholarship.objects.all()
    data = {
            'query_results':query_results,
            'form': form,
           }
    return render(request, 'hrfinance/add_remove_scholarship.html', data)

在您的模板中

<div align="center" >
    <form method="POST" onsubmit="return validation()" action="">
    {% csrf_token %}
    {{ form.errors }}
        <p>Upload File: {{ form.doc }}</p>
        <p>Faculty: {{ form.faculty }} </p>
        <p>Opening date: {{ form.startDate }} </p>
        <p>Closing date: {{ closeDate }} </p>
        <button type="submit" name="AddUser" value="Add Scholarship" onclick="add()"  >Add Scholarship</button>
    </form>
</div>
    <table  id="example" class="display" cellspacing="0" width="100%" border="1.5px">
        <tr align="center">
            <th> Scholarship </th>
            <th> Faculty </th>
            <th> Open Date </th>
            <th> Close Date </th>
        </tr>
        {% for item in query_results %}
        <tr align="center">
            <td>{{item.doc}}</td>
            <td>{{item.faculty}}</td>
            <td>{{item.openDate}}</td>
            <td>{{item.closeDate}}</td>
        </tr>
        {% endfor %}
        </table>

无法将字段中的值添加到数据库Django中
