no dear friend i don't want write genres when genres are defined!!!
only i want write"qwerty" when genres are undefined
for example i have 3 movies
1- Crash-[1080p]-[Crime].mkv
2- Lukochuri-[480p]-[].mkv
3- Blue Jay-[1080p]-[Drama].mkv

i want first and third movies go to "movies" folder no "drama" or "crime" folder!!!
but second movie that hasn't genre go to "qwerty" folder
do you see???

I gotcha.... So you are wanting to do a simple if then else statement. If genre is defined ignore it...and if it isn't defined then use xxxxxx folder.

Code: Select all

M:/{vf == /2160p/ ? 'Movies 4K' : vf =~ /1080p|720p/ ? 'Movies HD' : 'Movies'}

That is how I start my code. It verifies the size of the movie (4k, HD, SD) and puts the movies into the correct folder. So for your case, try this (M is my media drive...use whatever yours is instead.):

Code: Select all

M:/{genre == null ? "qwerty" : "Movies"}/

You could do this:

Code: Select all

any{genres; "Yes Genres"}{"No Genres"}

This code works due to the Unwind-on-Undefined Behaviour. Checking for null won't work, because the {genres} does not yield a null value when undefined, but throws an exception yielding no value at all.

Ahhh.. I tested it using other fields as I don't have any movies currently that don't have a genre listed. I wasn't aware it wouldn't give a null. And I was so proud of being able to help someone. DOH! LOL

well he was asking for it do nothing if genre found, so this will not do

Code: Select all

any{genres; "Yes Genres"}{"No Genres"}

the only way I can make it "do nothing" it this:

Code: Select all

{ (any{genres; 'Yes Genres'}{'No Genres'}).replace(/Yes Genres/,'') }

but what he really wants (I think) is this:

Code: Select all

{any{genres; genres.take(1)}{'qwerty'}}

or is it this way ?

Code: Select all

{any{genres; 'movies'}{'qwerty'}}/{ny}

[rednoah]

Why not just return an empty String?

Code: Select all

any{genres; ""}{"No Genres"}

[kim]

well for a very good reason.... does NOT work

Code: Select all

{any{genres; ""}{'qwerty'}}

ALWAYS output

qwerty

[rednoah]

I see. I guess "" is also evaluates to Groovy Truth FALSE and so it moves on.

I guess it'll have to return at least a non-Empty String to work:

Code: Select all

any{genres; ' '}{'querty'}

My 2 cents on the issue:

For months now, the check in my code for (no genre exists) has failed and caused an error - and I think this is the original poster's question:

Code: Select all

If a genre exists then
   Show me nothing
Else
   Show me 'qwerty'
Endif

I use:

Code: Select all

{((genres ?: ['GENRE']))}

but I now get

Code: Select all

[Expression yields empty value: Binding "genres": undefined]

I have been unable to find any way around this.

The simplest (theoretical) answer is

Code: Select all

{((genres ? "": ['qwerty']))}   <--- show a blank if a genre exists, else show 'qwerty"

but it doesn't work...
