I would like to update the Main_Page of our wiki from a script run by cron.
Apart from the page content itself, in pagecontent.old_text, what else do I need to update?
If I only update the "old_text" field, the new content is not displayed. I get the previous content, presumably from a cache somewhere. In LocalSettings.php I have $wgMainCacheType = CACHE_NONE;. So I guess that I need to also update something else in the Mediawiki database?
(In case it matters, this is with Mediawiki 1.31.10 on Debian 10 with Apache and PostgreSQL)
Use maintenance/edit.php, the edit API, Pywikibot etc. Trying to do changes via direct DB manipulation is a rather bad idea.
Updating the timestamp in page.page_touched works to have the wiki show the new content.
This example is using a PostgreSQL database, so it might need some adjustments if used with the more common MySQL DB.
To update the text of a page identified by it's name, it is necessary to join the page, revision and pagecontent tables. This example updates a page named "Drafts":
UPDATE pagecontent
SET old_text = 'New page content'
FROM page, revision
WHERE page.page_title='Drafts'
AND pagecontent.old_id=revision.rev_text_id
AND page.page_latest=revision.rev_id;
And to update the page timestamp so that the wiki shows the new content:
UPDATE "page"
SET page_touched = now()
WHERE page_namespace = '0'
AND page_title = 'Drafts';
An alternative which avoids tinkering with the database directly, is to use an extension like External Data. There are examples here to embed a text file in a page, and here to embed the output of a database query.
Using 2sxc to create a new app with only:
- One content type
- 15 rows of data
- One view (razor, single cshtml file)
When I call the #foreach loop, only some of the data is shown in the list view (apparently the ones inserted in the current dnn module and only through the "new" button in the toolbar). If I add the row in the admin panel, it will not show. When I deleted the module and inserted it again, I can see the data in the admin panel, but not in my list view.
Attached screens.
I tried calling the data with:
#foreach(var Content in AsDynamic(Data["Default"])){...}
or
#foreach(var e in List.OrderBy(e => e.Content.Farmaco).Where(e => e.Content.Cat == "1")){
var Content = e.Content;
... }
but the result is the same.
Am I missing something really obvious?

Yes, you're clearly not familiar yet with "raw data" and items-assigned to a modules.
In our code you get the module-data with Data["Default"], whereas the raw-data you would get from a query (then also with Data["Default"] or Data["Whatever-Name-Your-Stream-In-Your-Query"])
If you want to work with all data, you would again use a query, or App.Data["TypeName"] and build on that.

Pretty new to Infopath here and I can't seem to google this right so i'm going straight to my last option!
I'm building a form in which a Dropdown list needs to change dependant on the value of another dropdown list
So If X = 1, Then Y = 3 etc.
I'm just not aware of the functionality of Infopath and how I can get something like this working.
Thanks.
What you are looking for can be described at the following post:
Auto-populating an Infopath form after selecting a drop down
Essentially you will be using the rules manager to indicate that when a field equals something it will populate another field with data related to it. Think of it as more complex vlookup. Additionally, the verbage you would want to use to google more on the subject would be along the lines of "infopath auto-populate field based on another fields value".
I recently started a new job with a company and my first task is to update some quite old software for them.
There is a big back story but basically the software was written in PB8 (around 1997) and no one within the company (including me) has had any experience with PowerBuilder before and as the newbie I have been tasked to update and maintain it until a replacement has been approved and can be developed.
We have the license for PowerBuilder 12.5 so I am using PB12.5 Classic to do everything. The original developer cannot be contacted for support and no documentation exists.
One thing I am trying to understand, that will be a huge help in the future, is how to determine where functions are defined and where variables get their values..
The example I am working on at the moment is the following scenario.
There is a data window with tabs, named tab_detail each tab displays different whatever little orange men are in the tree list.
One of these are called dw_detail which allows pasting of data. None of the other tabs allow pasting of data, but I would like them to. dw_detail has an event rbuttondown() with the following code in it:
Window w_parentwin
If ib_add_mode Or ib_chg_mode Then
w_parentwin = Parent.GetParent().GetParent()
m_dwpaste m_pop_paste
m_pop_paste = CREATE m_dwpaste
m_pop_paste.idw_data = This
If ii_agent_code > 0 And Not IsNull(id_period) And Clipboard() <> "" Then
m_pop_paste.m_popup.m_paste.Enabled = TRUE
Else
m_pop_paste.m_popup.m_paste.Enabled = FALSE
End If
m_pop_paste.m_popup.PopMenu(w_parentwin.PointerX(), w_parentwin.PointerY())
DESTROY(m_pop_paste)
End If
When I add that code to the rbuttondown() event of tab number 2 (dw_adjustment) tab 2 now allows paste when I right click within the dw_adjustment data window but the data gets pasted to the fields within the dw_detail tab not the fields on the dw_adjustment tab.
I have tried debugging and stepping through the code but there are thousands of values in the variable window and without the ability to search I cannot find the variables used above and what their values are or why data gets pasted to the dw_detail tab instead of the dw_adjustment tab when I paste into the dw_adjustment tab.
Basically I am looking for any helpful tips on where to look or what the above is doing and why everything pastes to tab 1 instead of the tab I clicked paste in.
If more detail is needed from code from a different location or more information is needed I am happy to provide it.
As suggested by Seki I found the m_popup when double clicked it came up with wf_pastereturn():
Integer li_idx, li_rows, li_dwrows, li_comm, li_seqno
String ls_approval_type
If tab_detail.tabpage_details.dw_detail.RowCount() > 0 Then
li_idx = 1
li_dwrows = tab_detail.tabpage_details.dw_detail.RowCount()
Do Until li_idx > li_dwrows
ls_approval_type = tab_detail.tabpage_details.dw_detail.Object.approval_type [li_idx]
If IsNull(ls_approval_type) or ls_approval_type = "" Then
tab_detail.tabpage_details.dw_detail.DeleteRow(li_idx)
Else
li_idx++
End If
li_dwrows = tab_detail.tabpage_details.dw_detail.RowCount()
Loop
End If
If li_dwrows > 0 Then
li_seqno = Long(tab_detail.tabpage_details.dw_detail.Object.seq_no [li_dwrows])
End If
li_seqno += 10
If Clipboard() <> "" Then
If tab_detail.tabpage_details.dw_detail.ImportClipboard(1, li_rows, 1, 4, 3) <= 0 Then
MessageBox("Invalid Data", "Unable to paste!", StopSign!)
Return -1
End If
li_rows = tab_detail.tabpage_details.dw_detail.RowCount()
li_dwrows++
For li_idx = li_dwrows To li_rows
tab_detail.tabpage_details.dw_detail.Object.approval_type [li_idx] = trim(tab_detail.tabpage_details.dw_detail.Object.approval_type [li_idx])
tab_detail.tabpage_details.dw_detail.Object.approval_no [li_idx] = trim(tab_detail.tabpage_details.dw_detail.Object.approval_no [li_idx])
tab_detail.tabpage_details.dw_detail.Object.agent_code [li_idx] = ii_agent_code
tab_detail.tabpage_details.dw_detail.Object.period [li_idx] = id_period
li_comm = f_new_commission(Long(tab_detail.tabpage_details.dw_detail.Object.value_of_work[li_idx]), id_period)
tab_detail.tabpage_details.dw_detail.Object.levy_payable[li_idx]= &
inv_rate.of_CalculateLevyPayable (Long(tab_detail.tabpage_details.dw_detail.Object.value_of_work[li_idx]), id_period)
tab_detail.tabpage_details.dw_detail.Object.comm_deductable [li_idx] = li_comm
tab_detail.tabpage_details.dw_detail.Object.commission [li_idx] = li_comm
tab_detail.tabpage_details.dw_detail.Object.seq_no [li_idx] = li_seqno
li_seqno += 10
tab_detail.tabpage_details.dw_detail.Object.agent_return_detail_create_date[li_idx] = Today()
tab_detail.tabpage_details.dw_detail.Object.agent_return_detail_create_user[li_idx] = SQLCA.Logid
Next
Clipboard("")
Return 0
Else
Return -1
End If
I modified the function to use the windows SelectedTab property. Data will now paste into the tab but in the wrong input fields. I looked further and the data columns for the ImportClipboard function do not line up.
How is the best way to change the order of the selected database columns?
Here is a screenshot of what I mean by tabs:
So within the main program window, there are the above tabs, within each tab (where the input fields are) there is a data window labelled with the dw_ prefix.
Thanks heaps for your help.
I think first you should do some short tutorials. Please check out these:
PowerBuilder Classic 12/12.5 guide/tutorials
These are short and useful.
On the other side you are able to select specific variables in your own "watch variable" list, so you do not have to search over the several variables. You can right click on the variable name and do a Quickwatch or you can Insert the variable name in the Watch window.

The action with a contextual menu is in 2 times :
handle the mouse right click to display a contextual menu
perform an action among the one or several actions provided by the popup menu
You shown the pbscript that is displaying the menu with PopMenu() if there is something in the clipboard (Clipboard() <> "") and maybe you did not noticed that the pasting action is somewhere else.
Look in m_popup: there must be some code inside that may be hard-coded to paste in dw_detail. If so, maybe that you could store in the window instance variables a reference to the currently processed dw for the contextual menu.
Something like :
datawindow idw_current in the instance variables
then in the rbuttondown() event idw_current = this (this being the datawindow the rbuttondown() event belongs to)
and finally in the menu reuse the id_current instead of a hardcoded dw_detail
Concerning your question about where the variables are modified: what you can do is searching the variables by their name (right click on the target or a single pbl or object then 'search'), and put a breakpoint on the lines where they are affected. If you run in debug mode (CtrlDCtrlT instead of CtrlR) you will be able to trace when a variable is modified.
Paste Problem
Pass 1
It's hard to tell for sure, but I'd look at the code of m_dwpaste.m_popup.m_paste.Clicked. The worse case scenario is that dw_detail is hard coded into that script; the slightly better case is that it has a more flexible routine in there, but somehow dw_adjustment doesn't fit into that algorithm.
Pass 2
With the new information, we can see that the code of wf_pastereturn() (I'm not sure how you got to this script, but this looks like the culprit) is not simply pasting, but doing a lot more that involves specific fields. In fact, it's not just pasting, it's importing the data, which means that it's assuming the contents of the clipboard are not only in a specific format, but match the data set of the DataWindow (see the Columns pane in the DW painter, and be careful not to confuse the data set part of the DataWindow with the UI part). The question is, do you want:
"Pasting" like copying text from Notepad into a browser form; just putting text into the current field?
"Pasting" exactly like the other DataWindow, including assumptions that all the same columns mentioned in the script are in both DataWindows?
"Pasting" something like this script, but customized for the data set in the new DataWindow?
These all require somewhat different solutions, combined with the differences I asked about in my comment about tabs vs. DataWindows.
Finding Stuff
I'm going to give an unapologetically biased point of view, because I'm the author of a tool that, among other things, helps you search PowerBuilder code called PBL Peeper.
If you're looking at code in the Browse tab, and you want to see other mentions of the variable, you can select it, right click, and either
search forward or back within the script
search for the object name in the tree on the left (it'll make more sense when you see it)
search either the rest of the object or the rest of the application
Finding where a variable is assigned is more difficult than it sounds, because of the multiple syntaxes that could be involved.
// assigns a value on instantiation
int i = 1
// assigns a value when executed
i = 1
// does not assign a value
IF i = 1 THEN
// assigns a value possibly if the parameter is passed by reference (kind of like a pointer to the variable)
f_foo (i)
Finding the setting of a variable can be helped by understanding variable scope. If the variable is local, you only need to search the script. If the scope is instance or shared, you need to search the object (as above, pretty easy) and its descendants (easy to go to a given descendant with an RMB on the treeview, harder to search on a set of descendants). If the scope is global, you want to search the entire app.
Finding where a selected function is declared is possible, but you need to know a little secret (or RTFM). The Find on the RMB menu uses the parameters from the Find page, so you need to set Portion Type to All, not just Scripts, to find where functions are declared. Alternatively, you can use the Lists / Scripts pages and find the script using the functions on that page (Find, QuickFind, Filter, etc...).
The tool has a plethora of functionalities that let you find, filter and sift through code to get at what you're after. The above is just a quick introduction.
Good luck,
Terry.
OK, in good old fashioned PHP MVC, I might use a model to hit the DB, send info to my PHP controller that I pass on to the View. In the View, I might take that info (say i ajax'ed my controller for the info) and create a table or ul to display the data returned.
I've had trouble finding any modern (ver 6.1 is what i'm on) tutorial to show me how to preform this action in typo3.
Can anyone just "steer" me in the right direction? Perhaps provide an example via answer, or some links to further information that may compare it down to "old fashioned MVC"?
Extension has been suggested, but I'd like to know the very base process of what I'm asking before I try writing some extension, unless the extension is the only way. Although, my table is now on the SAME DB my typo3 is on, so shouldn't there be some command to just simply call my table and get the rows? Maybe send them to a ###sub-part###?
You can use a typoscript cObj content and the select option together with the function render_obj when your table name is like the typo3 nameing convention. The select pulls the record from the table and pass it to the render_obj function. It's a function that can apply to all cObj and iterate over the entire selection. stdWrap works only on the entire cObj. When you need to work through each record you need the render_obj function. For example:
10 = CONTENT
10 {
select {
pidInList = 1
where = colpos=1
orderBy = sorting
}
table = tt_content
renderObj.stdWrap.wrap = <li>|</li>
renderObj.stdWrap.required = 1
}
10.stdWrap.wrap = <ul>|</ul>
This gives you an unorderd list from the tt_content table with pid=1 and the content from the far left column.
