Searching for User Parameters

[pspeirs]

Hi All,

I'm trying to find a user parameter via a keywork (tag) search rather than the parameter name much like I can do it with other types.  I've looked at running a sql query in a function to do it however I can't seem to associate a keyword with the parameter name.

I can use: 

SetUserParam('Local Network', 'w_obs_wind_dirtext', value) 

however I want to set the value based on the keywork like

SetCBusByKW({'irrigation_current_runtype'}, 'or', {target = 1, ramprate = 0})


I have some db helper functions like the below, so not opposed to doing something in a query.


function db_GetObjectByTag(tag)

    -- Return a table of object parameters based on the id
    local query = string.format('SELECT * FROM objecttags WHERE tag = "%s"', tag)
    liste = db:getall(query)

    if (table.maxn(liste) ~= 0) then
        return liste
    else
        return false
    end
   
end





Cheers,
Paul

Why don't you use build in function?
myobjects = grp.tag('tag')

I don't have that function on the SCAC available for user parameters. The logic machine is very similar, but with some mods. A lot of the info on this forum is applicable, particularly around the lua scripting options.

User parameter is standard LM object so grp.tag should work. Have you actually tried it?

[Daniel]

I tried it on NAC and it works

[pspeirs]

Yep. tried it and it works for a read, is it possible to write using a similar methos via tag?

It depend what you want to write.

[pspeirs]

Pretty much anything that can be written to a user param, string, integer, float.

[admin]

Writing is done like this:

Code:

value = 123
objects = grp.tag('tag')
objects:write(value)

Awesome, thats what I need, thanks. Is there documentation available on this type of thing, the CBus documentation is pretty basic.

Cheers,
Paul
