Lianja 4.2 Query Picker

[barrymavin]

I've been looking at ways to provide a consistent way to query and select an item from related tables as this has been asked on numerous occasions.

In Lianja 4.2 we already have the "Custom Query Builder".

I have now combined "Miller Columns" with a browsable and searchable data grid.

The cascading lists of the "Miller Columns" and the data grid have a small "Search" icon which when clicked slides in the query builder allowing you to filter the individual columns and grid.

I'm still refining this prior to general release. It operates across desktop, web and mobile. I will document its usage in due course.

A picture says a thousand words. See below.

The "Query Picker" is now fully working across desktop, web and mobile. Doc to come. This is included in 4.2Beta14.

Hi Barry
it's fantastic.

in the demo, what is the fourth parameter?
Lianja.showQueryPickerPanel("Browse Orders", "myCallback()", "southwind", "order_details");

I suppose it is "what needs to be analyzed", but I do not find how it is defined.

thanks
Fabio

Hi Fabio,

I'm currently documenting it.

https://www.lianja.com/doc/index.php/QueryPicker

So read through that doc if if you have any questions let me know. I'll add some additional explanations regarding params.

Hi Barry, I'm tryng.. without a good results..
but I've a question:
if I need to browse only one table.. it's possible?

[phabio]

Now, I'me try with this parameters:
database=southwind&
table=products&
tabletitle=Item Details&
selectcolumn=productid&
columncount=1&
columntitles=Categories&
columns=categories,categoryid|products,productid,p roductname,categoryid={}&
columnsorderby=||&
picklist=products|productid,productname|categoryid ={}

but don't work.

Hi Fabio,

See the latest updates to the parameters table. The {} should be encoded: %7B%7D

YES!

now is better..

this work

m_par = [database=southwind&table=products&tabletitle=Item Details&selectcolumn=productid&columncount=1&columntitles=Categories&columns=categories,categoryid|products,productid,categoryid=%7B%7D&columnsorderby=||&picklist=products|productid,productname|categoryid=%7B%7D]
Lianja.showQueryPickerPanel("Browse Items", "", "southwind", "products", m_par, 900)

2 questions:
is possible to add a column to the "Coategories?

I've try with

m_par = [database=southwind&table=products&tabletitle=Item Details&selectcolumn=productid&columncount=1&columntitles=Categories&columns=categories,categoryid<b>,categoryname</b>|products,productid,categoryid=%7B%7D&columnsorderby=||&picklist=products|productid,productname|categoryid=%7B%7D]
Lianja.showQueryPickerPanel("Browse Items", "", "southwind", "products", m_par, 900)

but not work

If I don't need to have 2 table?
It's possible to only have the products table?
