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.

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.

@ 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.

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.

Do you have a Valentina Studio Pro license? Editing is available only in Pro version.

@Sergey Pashkov what I mean is I only want the actor_id, first_name and last_name fields only on the report excluding last_update field. How can I set this in Valentina studio? Please see the image attached.

1. Create this query on the project tab and add a parameter with some default value on the Parameters tab of the following dialog (vs_add_parameter_query.png)
2. Create a report with this query
3. Report is generated with a default value of the parameter.

Now the report is generated using the default value.

It is also possible to set the parameter value interactively within the Valentina Studio but in ADK code we use rerport.setParameterValue method (not available in Python yet)

Valentina for Python doesn't have the necessary methods in the current version, we have to create a new build.
Do you only need to run it on Windows now?

Sorry, reread it again, not very clear.

For example, the base query is SELECT * FROM table1

Conditionally, you need to change it to e.g. SELECT * FROM table1 WHERE f1 > 5

Right, or do you want something else? A little example would help.

@Sergey Pashkov I want to do something like the image below.

I want to set a parameter for any Item No on my report to get specific fields of a particular product including image field.
Example : SELECT * FROM items WHERE item_No =$P(pItemNo);

Thus the Item No can be any Item No not a specific Item No that can display specific XXXXXXX records on report as shown in the image.

That is strange, could you please try to install the latest version?

Here is my test code:


#!/usr/bin/python3



# Location of the extension (if need)

import sys

sys.path.append('./..')



# Import extension

import valentina



# Open local project

project = valentina.project.connect('file://c:/Users/sergey/Documents/Paradigma Software/VPython_x64_12/Examples/valentina_sakila_reports.vsp')



# Make report instance

report = project.report(name='Report_FilmList', dsn='sqlite://c:/Users/sergey/Documents/Paradigma Software/VPython_x64_12/Examples/sqlite_sakila.db')

report.setParameterValue( 'pFilmID', '5' )

# Print result as PDF

report.printToDisk('./Report_FilmList.pdf')



# Cleanup

report.close()

project.close()


Also, maybe you can start a new discussion with a more narrow topic for easier navigation?

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.
