HI,
i'm new to valentina suite. I saw the tutorials on how to download and install valentina studio,valentina server and valentina ADK. I want to embed valentina report in my python code but I can't find any video tutorial on that. i saw saw for java implementation. I would appreciate if I'm assisted with the steps to achieve this task. Thanks in advance.

Oh you mean I cannot set these parameters even in the free version?

You cannot edit a report in a Free version - including defining a parameter.
But if it is already defined - you can set the value for it.

We've generated a temporary Valentina Studio Pro key for you to try.
Please check out the private messages.

@ Sergey Pashkov

I have a search field in my python application that displays records based on the actor_id the user will type in the search field.

Example:
SELECT * FROM actors WHERE actor_id = 24 will display information on actor with the ID 24 when user type 24 in the search field as in the image.

I want the information displayed in my GUI application to show on my report how do I do that in Valentina studio? Because I want the actor_id to be what the user types not a specified actor_id.

In python with sqlite I know the syntax is SELECT * FROM actors WHERE actor_id = ? but I don't know the query syntax in Valentina Studio

That's exactly what parameters are used for:
1. Start to create a new query
2. Define text as:
SELECT * FROM actors WHERE actor_id = $P(pActorID)
3. Add pActorID parameter on Parameters tab, here you can define its default value

On preview, a report with the default value will be generated.

But that's it for now - Valentina for Python is a relatively new ADK, necessary methods are not available yet. It should not be hard to add them.

Please check what I did and the result in the image below. Is that the desire result to obtain?

Almost - just add a default value and maybe change the type of parameter to an integer.

I have done as instructed in the image below , I think the Default Value should be same as 00000 right? but I'm still seeing the value 0 on the report when preview.

No, it's should be a valid value from the table.

@Sergey Pashkov Please can you use the table in the picture below to give the valid value you mentioned above. I'm a little bit confused.

1 (or any value from the table), it is necessary only for development.

@Sergey Pashkov from your recent reply you mean when I choose 1 as the valid value the following records will be obtained right?

actor_id first_name last_name last_update
1 PENELOPE GUINESS 01/24/2013 01:41:44:522

What if I don't want to input a specific actor_id say 1 as the valid value but instead I want the user to choose a random actor_id?

In Valentina Studio, you can create an interactive parameter and set arbitrary parameter value.
In Python, there will be report.setParameterValue( “paramName”, “value”) method for it. But in the next version.

Please when is the release date for the next version? This feature is very important to the project I'm working on.

We plan to create a test build with new methods for you to try, so no need to wait for a new complete release.

I've uploaded a test build with the report.setParameterValue method added.

How to use it:

# Make report instance
report = project.report(name='Report_FilmList', dsn='valentina://./valentina_sakila_bl.vdb')

report.setParameterValue( 'pFilmID', '2' )

# Print result as PDF
report.printToDisk('./Report_FilmListq.pdf')
