Delete dedecms custom Fields

When you modify a website, you need to add custom fields. When you do not need them later, you will find that custom fields cannot be deleted.

So I found the dede_addonarticle table of the database and saw the Custom field. After deletion, I found that the custom field still exists in the background model. Many of my friends have done this, I don't know how to do it. An error occurred while publishing the article, prompting that the custom field could not be found, but the article could not be published.

This custom field exists in dede_channeltype, that is, in the model configuration. Enter the dede_channeltype table of the database and Click Browse content, you will find that this custom field exists in the content of the fieldset field.

Reference content is as follows:
<Field: Body itemname = 'Article content' type = 'htmltext' isnull = 'true' default = ''rename = ''page = 'split '/>
<Field: daima itemname = "code" autofield = "1" notsend = "1" type = "htmltext" isnull = "true" islist = "0" default = "" function = "" maxlength = "" page = "">
</Field: Daima>

You only need to delete <field: Your field> </field>. The problem is solved.
