Django-HTML：我如何允许用户添加额外的输入字段（确保它们不是必需的）？ 类似于 + 按钮的东西

Question

Django-HTML: How can i allow users to add additional input fields (ensuring they are not required)? Something like a + button. I only want to display info 1. And only when users press the '+" button, these fields will appear and allow them to add info_2 and info_3. Is this possible? Because do i need to provide like an additional field in the model.py: eg info_4 =..... info_5 =.......

I have searched the Stackoverflow but was unable to find a question and answer very similar to this. Maybe someone can advice on the coding as i believe your input will be very beneficial to both django and html beginners:)

models.py

class BlogPost(models.Model):
 title                  = models.CharField(max_length=50, null=False, blank=False)
 body                   = models.TextField(max_length=5000, null=False, blank=False)
 info_1 = models.TextField(max_length=300, null=False, blank=False)
 info_2 = models.TextField(max_length=3000, null=False, blank=False)
 info_3 = models.TextField(max_length=300, null=True, blank=True)

html:

  <form class="create-form" method="post" enctype="multipart/form-data">{% csrf_token %}
   <!-- chief_title -->
   <div class="form-group">
    <label for="id_title">Chief Title!</label>
    <input class="form-control" type="text" name="chief_title" id="id_title" placeholder="Title" required autofocus>
   </div>

  <!-- Body -->
  <div class="form-group">
    <label for="id_body">Full Description</label>
    <textarea class="form-control" rows="8" type="text" name="body" id="id_body" placeholder="This is about..." required></textarea>
   </div>

  <div class="form-group">
    <label for="id_Info_1">Info_1</label>
    <input class="form-control" rows="10" type="text" name="Info_1" id="id_Info_1" placeholder="Info_1..." required></input>
   </div>

forms.py

class CreateBlogPostForm(forms.ModelForm):
    class Meta:
        model = BlogPost
        fields = ['chief_title', 'body' , info_1' ]

Answer 1

You can create a seprate Model called Info and add a ForeignKey relationship to a post , then the post author after its creation could add as many info objects as he would want.
