Can I refresh a relationship?

[J__]

Hi,

I have typical master- 1 - M - <details relationship set up.

I also created another relationship against it to include the above but also based on a condition of a field. For example the field might have "Drum", "Guitar" or "Piano"

I want to count the number of Drum records and Guitar records and Piano records so i came up with this idea to use a relationship and I guess kind of a filter.

I add a record to my first relationship - a new child. But when i get the count from one of my other relationships like DrumRelation or PianoRelation the count is off by one. Is there anything i need to do to force a refresh?

thanks

Try enclosing the Count function within Evaluate.

Evaluate( "Count(yourrelationship::serial)"; triggerfield )

If that doesn't work, stuff and attach the file.

I'm doing this from a script can i still use this?

sorry i'm not that familiar with evaluate - i just looked at the help , it looks very powerful.

serial is where you mean the key correct?

could you elaborate on the triggerfield?

do i need to use that? in a script how would that work, since evaluate wouldn't trigger until script is run.... isn't it optional?

thanks,

sincerely,

Relationship currently is based on a text field. I would like to change all to a numerical key field and base the relationship on that. Is this possible?

TIA

Hi, Wizard. It's on the forum main page (see attachment).

Thanks Jim,

J, what does your script look like? It sounded as if you were strictly using a relationship, which is why I suggested the calculation. If you are scripting it, the process may be much easier.

Queue,

thanks so much for the response.

I have a Master - basically a Project, which has associated with it one or more Tasks.

Simple enough. So i use 1-M. Turns out you can specify what type of task it is, I have a drop down where you pick from a list of job types. They can be 3 types D, M, P

and the Task number needs to reflect this. in the format yynnn<jobtype><number>

where yy = year, nnn = number 3 digi number 000-999, jobtype [ D | M | P ] and <number> is 0 to however many jobs of that type are created.

example: 04000D1, 04000D2, 04000M1, 04000P1, 04000P2, so you can look at the number and know what type of job it is. To create these number sequences and they must be in sequence, you must know how many D jobs there are already and how many P and so on.

this is purely to create a visual number, which the user can refer to, but under the hood, my relations, to say customers do not use this number, I use a serial

So, my approach was to create a relation from the project-Tasks, called DJobsRel

with the following criteria:

prj_id -- prj_idFk and

gDConst = jobtype,

job type is the field in the job table which specifies what that the job is D or whatever

I have a global holding a 'const' , gDConst = "D". So, basically this gives me a query of all D records in the table.

I have one of these for each job type.

I then (in a script) when the new job needs to be created with this special id, which is based on the drop down they pick in the job... i do something like this

if [jobs::jobtype = "D"] /* D job type */

Set Field [jobs::job_id; jobs::prj_id_fk & "D" & GetAsText( Count( DJobRel::uid) +1)]

end if

if [jobs::jobtype = "D"] /* D job type */

Set Field [jobs::job_id; jobs::prj_id_fk & "D" & GetAsText( Count( MJobRel::uid) +1)]

end if

my jobs::prj_id_fk is already something like 04nnn, so I get when i concatenate

04001D1

04002D2

04003M1

04003M2

i show them in a portal and i sort them so they are grouped together in the portal.

it looks to me like sometimes i when i do count, the count is behind and so I'll get 2 numbers with D1 in them. That's what the refreshing was about.

sorry for the length of post, hope that makes it clearer.

sincerely,

See if the attachment works for your purposes. It doesn't require any scripts or globals, just an extra relationship in the Tasks table.

Note that once a Type is selected, the record must be committed (you have to click out of the portal or press Enter) before the next related record can be created correctly.

Queue,

thanks for the sample, I appreciate it very much. This has some good points to it. I'll try to absorb it.

thanks again so much.

I'm getting that refreshing problem again. How can I do this with a Script?

thanks,

You mean how can you auto-commit records after adding or changing the Type? You could probably use EventScript to trigger a Commit Records script. You could also change the menu to be a list and attach it to a script that runs a loop, waiting for a selection, then Commits the request. See here for a discussion and some sample scripts about triggering a script using a pop-up list on a Mac.

Queue - right that is what i have been trying to do. I actually read through your link and your articles/discussions.

I wound up putting a global in the Master table (Projects) which does a count ( jobRel::uid )

although i do not display this global anywhere, i have it set to be unstored, wouldn't this force the relation to refresh maybe?

It seems like this works ... so far... what do you think?

I did try putting the script ( CreateID ) under that drop down, but the count was a little weird.. but i was a little tired, so it maybe ok now.. have to revisit.

thanks!

sincerely
