Question

Web开发Django和python的新手。

有一个带有文本框的评论页面，客户可以在其中写下有关工厂访问的评论。单击提交后，它将以文本文件形式发送到Manager邮件。

我的雇主希望它更像调查页面，因此他们要求将文本框输入更改为基于表单的输入，其中客户提供了多个标签和输入，如下所示。单击提交后，应使用以下信息创建一个文本文件，然后以邮件形式发送。

Name : 

Phone :

email :

precaution and safety gears given: [yes/no]

Unit 1 ambience: [Very satisfied/Satisfied/Neutral/Unsatisfied/Very unsatisfied]

Unit 2 ambience: [Very satisfied/Satisfied/Neutral/Unsatisfied/Very unsatisfied]

Unit 3 ambience: [Very satisfied/Satisfied/Neutral/Unsatisfied/Very unsatisfied]

General feedback : /text box for detailed review if any/

[]中给出的

值为下拉值。

我们的网站基于Django框架构建。以下是评论页面上使用的模板文件。

{% extends 'page1.tmpl' %}
    <form id="reviewform" method="post" action="/sjfacweb/revfile/save">
        <pre><textarea name="review" id="review">{{ review }}</textarea></pre>
        <input class="button" type="submit" name="submit" value="Save" />
    </form>
{% endblock content %}

views.py

@require_POST
@csrf_protect
def revfile_save(request):
   """
   This page processes and saves review file.
   """
   review = request.POST.get('review', "").replace('\r\n','\n')
   reviewfile_name = "/root/sjfacweb/" + remote.sjfacweb()
   remote.write_reviewfile(reviewfile_name,False,review)

我认为django变量'review'捕获了客户键入的整个字符串并将其保存为文件。

假设模板如下所示，

{% extends 'page1.tmpl' %}
    <form id="reviewform" method="post" action="/sjfacweb/revfile/save">
        Name: <input type="text" name="Name" value=""><br>
        Phone: <input type="text" name="Phone" value=""><br>
        email: <input type="email" name="email" value=""><br> 
        precaution and safety gears given: 
        <select>
            <option value="yes">yes</option>
            <option value="No">No</option>
        </select>
        <br>
        Unit 1 ambience:
        <select>
            <option value="Very Satisfied">Very Satisfied</option>
            <option value="Satisfied">Satisfied</option>
            <option value="neutral">neutral</option>
            <option value="Unsatisfied">Unsatisfied</option>
            <option value="Very Unsatisfied">Very Unsatisfied</option>
        </select>

        <pre><textarea name="review" id="review"></textarea></pre>
        <input class="button" type="submit" name="submit" value="Save" />
    </form>
{% endblock content %}

如何将表单中的所有标签/值转换为单个字符串并分配给django变量{{review}}？

谢谢

在Django中，应该使用Django Forms完全处理表单，因此最好在您的应用文件夹中创建一个forms.py文件，然后执行以下操作：

from django.forms import forms

class ReviewForm(forms.Form):
    PRECAUTIONS_CHOICES = (
        ('no', 'No'),
        ('yes', 'Yes')
    )
    UNIT1_CHOICES = (
        ('Very Satisfied', 'Very Satisfied'),
        ('Satisfied', 'Satisfied'),
        ('neutral', 'neutral'),
        ('Unsatisfied', 'Unsatisfied'),
        ('Very Unsatisfied', 'Very Unsatisfied'),
    )
    name = forms.Charfield()
    phone = forms.Charfield()
    email = forms.EmailField()
    precautions = forms.ChoiceField(choices= PRECAUTIONS_CHOICES, widget=forms.Select())
    unit1_ambience = forms.ChoiceField(choices= UNIT1_CHOICES, widget=forms.Select())
    review = forms.CharField(widget=forms.Textarea())

    def clean(self):
        # after checking every field is available and then concat values to each other

        if 'name' in self.cleaned_data and 'phone' in self.cleaned_data and ... :
            name = self.cleaned_data.get('name')
            phone = self.cleaned_data.get('phone')
            ...
            review = self.cleaned_data.get('review')
            expected_string = name + '\n' + phone + ... + review
            # concat all with review and then return string
            return expected_string

然后在您的视图函数中执行以下操作

from .forms import ReviewForm

def revfile_save(request):
    form = ReviewForm(request.POST)
    if form.is_valid():
        review = form.cleaned_data

您甚至可以创建类似def clean_name(self)的方法并在输入之前检查输入是否为空或在每个字段上进行更多验证清洁方法称为

请注意，您可以使用Django表单和ModelForms做更多的事情，因此最好阅读文档
