Odoo14 | about the abnormal display of statusbar keyword after use and Its Solutions

Today I met an interesting bug, I'll follow odoo14 Code in the development manual , Because the teaching structure of the textbook is written according to the function , There are differences in the code descriptions before and after , There have been some conflicts , What I met today is based on state The field of the status bar bug

This is my field

state = fields.Selection(
        [('draft', ' Unavailable '),
         ('available', ' You can use '),
         ('borrowed', ' Lent out '),
         ('lost', ' Lost ')], u' state ', default='draft')

As shown in the figure below

<header>
    .... Here is the code of the button part, so it is omitted 

    <field name="state" widget="statusbar"/>
</header>

The reason why this place is like this , This is not because the code is written incorrectly  

But in the previous chapter , stay form In the lower half of the view, there is also a state Display of fields

               ....... It's on it form The top half of the view 
                 <group>
                    <group>
                        <field name="name"/>
                        <field name="author_ids" widget="many2many_tags"/>

                  ->      <field name="state"/>    <-  you 're right , This is the line of business 

                        <field name="pages"/>
                        <field name="age_days"/>
                        <field name="publisher_id"/>
                        <field name="publisher_city"/>
                        <field name="notes"/>
                    </group>
                .........

Comment it out or delete it , Installing or upgrading modules

Now the status bar can be displayed normally

  analysis ：state The common field of does not comment will conflict with the status bar without error , The status bar will be displayed as a normal enumeration field
