QUESTION
I'm on Spring Boot v1.5.3 and when I use Hibernate inheritance, AnnotationException: mappedBy reference an unknown target entity property
occurs when there are properties with the same name in both parent and child entities.
For example:
...ANSWER
Answered 2020-Oct-14 at 07:47The truth is that I have never encountered a similar problem, the logical thing, and a good practice would be to change the name of the property to differentiate which entity each one refers to, the compiler will tell you where to change it.
You could try indicating the child class in the relation as follows:

QUESTION
Despite multiple entries here that seem to have a similar issue i can not get this really working.
I have a Setup of two depended DropdownButtonFormFields where the second changes to another list after the first is changed.
- I was able to break down the issue to the persistent remaining of the selected value of the second selection. I expected it to change with my provided value information in the code.
The following error is provided
...ANSWER
Answered 2020-May-13 at 23:49I found a workarround on the issue.
It seems like instead of rebuilding the DropDownFormField, Flutter just considers it as completely ok to keep it. In this case it is also even pretty stubborn.
As i could not find a way to rebuild the Field, I created a pretty nasty but working. Also still requires some polish.
I basically let flutter believe I provide a different widget each time.
QUESTION
I have the interface:
IColored that guarantees the function getColor.
Now I have two objects:
1. Ferrari
2. RedApple
that both implement this interface/function in the same way.
(But cannot inherit from the same object - no multi-inheritance allowed).
How would you avoid code-duplication?

QUESTION
I have a simple Python 2.7 enum:
...ANSWER
Answered 2017-Apr-10 at 15:11In Python 3.6 and aenum 2.0
12 (which is compatible with 2.7 and 3.0+) a new method has been added: _missing_
2.
This method is called just before a ValueError
is raised to give custom code a chance to try and find the enum member by value. Unfortunately, this makes it unsuited for your use-case -- looking up by name.
Fortunately, aenum
has the extra option of defining a _missing_name_
method3 which will be called when name lookup fails.
Your code above should look like this:

ANSWER
Answered 2020-Feb-17 at 07:49Started from c# 7.0 switch statement has become more powerful and covers a lot of scenarios.
But to answer your question in shortest way you need to put a constant value in your case field. You can try putting a variable or another string property from Food inside switch statement, but it won't work either because switch is looking for a constant value.
You can look at the microsoft docs on switch statement.
