Question

我创建了一个自定义视图，该视图以类似手风琴的方式组织了我所有的产品和服务，因此数据是用户友好的。下面是我的自定义视图：

class productView(BaseView):
    form_columns = ['name','price']
    @expose('/')
    def index(self):
        myServ = Product.query.all()
        myProd =  Productcategories.query.all()
        return self.render('admin/products.html', myProd = myProd, myServ = myServ)


admin.add_view(productView(name='Products and Services', endpoint='products'))

然后我继续制作HTML视图，该视图的效果非常好。我现在所处的位置是我创建了一些按钮，这些按钮使用我的jquery来加载模态。那也很好。但是，我有些犹豫。

点击“提交”按钮后，如何告诉它添加/删除/编辑特定项目？

//button scripts
$(document).ready(function() {
  $(".add-category-item").click(function() {
    $('.bg-modal').fadeIn('slow');
  });

  $(".close").click(function() {
    $('.bg-modal').fadeOut('slow');
  });
});

$(document).ready(function() {
  $(".subtract-category-item").click(function() {
    $('.bg-modal').fadeIn('slow');
  });

  $(".close").click(function() {
    $('.bg-modal').fadeOut('slow');
  });
});

$(document).ready(function() {
  $(".edit-category-item").click(function() {
    var parent = $(this).attr("data-parent");
    $('#papa').val(parent);
    console.log("the parent caregory is:" + parent);
    $('.bg-modal').fadeIn('slow');
  });

  $(".close").click(function() {
    $('.bg-modal').fadeOut('slow');
  });
});

<a class="edit-service-item" href="#"><span class="glyphicon glyphicon-pencil"></span></a> <a class="subtract-service-item" href="#"><span class="glyphicon glyphicon-minus"></span></a> <a class="add-service-item" href="#"><span class="glyphicon glyphicon-plus"></span></a>


<!-- Modal -->
<div style="display: none;" class="bg-modal">
  <div class="modal-contents">

    <div class="close">+</div>

    <form action="">
      <input type="text" placeholder="Name of category">
      <input type="text" id="papa">
      <a href="#" class="button">Submit</a>
    </form>

  </div>
</div>

如果您不使用flask-admin通用删除和编辑视图，则可以公开一条将为您执行删除/编辑的路由，并将此路由添加为表单action

例如

class productView(BaseView):
    form_columns = ['name','price']
    @expose('/')
    def index(self):
        myServ = Product.query.all()
        myProd =  Productcategories.query.all()
        return self.render('admin/products.html', myProd = myProd, myServ = myServ)

    @expose('/custom_delete')
    def custom_delete(self):
        # write custom code to delete from the database
        return self.render('admin/products.html', myProd = myProd, myServ = myServ)

然后在您的HTML中

<div style="display: none;" class="bg-modal">
  <div class="modal-contents">

    <div class="close">+</div>

    <form action="{{url_for('.custom_delete')}}">
      <input type="text" placeholder="Name of category">
      <input type="text" id="papa">
      <a href="#" class="button">Submit</a>
    </form>

  </div>
</div>

您的表单将提交到端点，您可以在其中处理后端的删除操作

使用flask-admin和sqlalchemy;现在我正在尝试制作一个表格来添加/删除/编辑我的表格
