mysql - How do I handle multiple types of users? -


Users in my application can be one of three types: teens, individuals or members of any organization. In my user table, I have a boolean field teen (not faucet) and a foreign key organization_id (null).

If the teen is true and Organization_id is zero, the user is a teenager Teenage can not belong to an organization.
If the teenagers are liars and the organization_id is empty, then the user is a person.
If the teenagers are liars and the organization_id is not empty then users are members of any organization. / P>

There should be a better way of doing this I do not like that this case exists where teens are true and organization_ID is not empty.

Would it be better to add a new table, the organization and remove the foreign key from the organization table? I see the negative side that it will take me more time to determine if a user is not an individual or organization, and get data if appropriate.

Is this another great way to handle?

If you had a role column that was either a teenager, individual or member. You can probably consider these roles as normal at their own table, and use a foreign key:

1 teen 2 3 individual members of an organization

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
