How can i make this code work in QGIS3?
canvas = iface.mapCanvas()
canvas.mapRenderer().setProjectionsEnabled(True)
canvas.mapRenderer().setDestinationCrs(QgsCoordinateReferenceSystem("EPSG:2154"))
Error

I have inherited an older project using jquery.
I am modernising the code.
In particular this $(selector).html("<h1>lol</h1>"); which as far as I understand is a full replacement of the selectors content.
I always end up with an error if I try to render to a cleared element.
This code:
const appDiv: HTMLElement = document.getElementById('app');
appDiv.innerHTML = `<h1>TypeScript Starter</h1>`;
// trying to replace jquery $(selector).html("<h1>lol</h1>");
appDiv.innerHTML = '';
render(html`<h1>lol</h1>`, appDiv);
appDiv.innerHTML = '';
render(html`<h1>lol</h1>`, appDiv);
Or see my stackblitz
I always get the following error:
Error in lit-html.js (93:55)
Cannot read properties of null (reading 'insertBefore')
Do you know what I am missing? 🧐
Thanks!
Note: This is a duplicate of my question (and based on a suggested technique) from a closed Lit Github Issue
Note: Maybe I am talking rubbish. I can't find a clear answer if render REPLACES content or APPENDS content. A concrete answer on that would be fine!
Lit v1 will clear the container before rendering the first time. Lit v2 will not.
Only clear the existing container content once before using render. After that render will correctly update content from previous render calls.
const appDiv: HTMLElement = document.getElementById('app');
appDiv.innerHTML = `<h1>TypeScript Starter</h1>`;
// trying to replace jquery $(selector).html("<h1>lol</h1>");
appDiv.innerHTML = '';
render(html`<h1>lol</h1>`, appDiv);
render(html`<h1>lol2</h1>`, appDiv);
I'm trying to run this example about how to use Flask-Admin displaying maps: https://github.com/flask-admin/flask-admin/tree/master/examples/geo_alchemy.
In README.rst, there's this instruction:
You will notice that the maps are not rendered. To see them, you will have to register for a free account at Mapbox and set the MAPBOX_MAP_ID and MAPBOX_ACCESS_TOKEN config variables accordingly.
I already have a valid MAPBOX_ACCESS_TOKEN, and I went to MapBox to look for a MAPBOX_MAP_ID. There I read that MAP_ID was deprecated, and now I'll have to obtain a tileset ID, and it's described as a label composed by <my_mapbox_user_name>.the_tileset_ID itself.
So I located the code as they described in the instructions (in my case, mapbox-streets-v8) and fulfilled the config.py parameters:
MAPBOX_MAP_ID = '<my_mapbox_user_name>.mapbox-streets-v8'
MAPBOX_ACCESS_TOKEN = 'pk.eyJ1...'
However, I couldn't see any map displayed or any error message.
How can I fix it?
I think there is a small bug in file Lib\site-packages\flask_admin\static\admin\js\form.js. The original URL generated to get a tile is:
https://api.mapbox.com/styles/v1/mapbox/<MAPBOX_MAP_ID parameter>/tiles/12/2258/2457?access_token=<MAPBOX_ACCESS_TOKEN parameter>
However, the correct one is:
https://api.mapbox.com/styles/v1/<MAPBOX_MAP_ID parameter>/tiles/12/2258/2457?access_token=<MAPBOX_ACCESS_TOKEN parameter>
That is, I had to remove the mapbox word from the URL.
To do that I made some changes in form.js file:
//var mapboxUrl = 'https://api.mapbox.com/styles/v1/mapbox/'+window.MAPBOX_MAP_ID+'/tiles/{z}/{x}/{y}?access_token='+window.MAPBOX_ACCESS_TOKEN
var mapboxUrl = 'https://api.mapbox.com/styles/v1/'+window.MAPBOX_MAP_ID+'/tiles/{z}/{x}/{y}?access_token='+window.MAPBOX_ACCESS_TOKEN
Then, it's working now:
I want to open a new tab with a gloda conversation from inside calendar code.
I receive an error from error console:
window not defined (or document not defined), depending on which of the two I use to Access tabmail:
let tabmail = window.document.getElementById("tabmail");
let tabmail = document.getElementById("tabmail");
The code works fine if the js file is included in an overlay xul-file.
But I want to use it outside of xul in my code.
Somewhere in my calendar code (in my 'addevent'), the same code throws the error.
This code is originally called from a rightclick on an email, but several layers deep into calendar code.
In MDN, I read that window is global? So what do I Need to do to add an tab?
This part works if tabmail is properly referenced:
tabmail.openTab("glodaList", {
collection: queryCollection,
message: aCollection.items[0],
title: tabTitle,
background: false
});
So how do I get a reference for tabmail?
Any help is appreciated.
after trying and looking through code for really some time before posting, it took only ca. 20 minutes to accidentally find the solution after submitting the question..
While browsing mailutils on mxr for something else, I found the solution in some function:
mail3PaneWindow = Services.wm.getMostRecentWindow("mail:3pane");
if (mail3PaneWindow) var tabmail = mail3PaneWindow.document.getElementById("tabmail");
I am trying to keep track of the current Y position on a PDF page created using FPDF so that I can correctly start a new page ensuring tables do not cross a page break. Firstly am I right in using GetY to monitor this and if so what is the correct syntax. I am trying
$currentYposition = GetY();
but it does not seem to work. Any advice?
No idea why this works - but it does:
If you just grab Y after the call, it seems to be the value before the MultiCell.
Grabbing it before and after and taking the difference gives you the height.
$oldY = $this->getY();
$this->MultiCell(150, 4, utf8_decode($description), 0, "L");
$newY = $this->getY();
$multiCellHeight = $newY-$oldY;
This one worked for me.
$y = $pdf->GetY();
I came to this question when programming in python and using the fpdf module. I'll post in case anyone else need this, I could not find this solution in the official documentation but for me following worked:
from fpdf import FPDF
pdf = FPDF()
pdf.add_page()
current_y = FPDF.get_y(pdf)
I'm trying to call a webservice from the play framework, and I think I'm doing it wrong. I have an example call to http://www.myweather2.com/developer/forecast.ashx?uac=eDKGlpcBQN&query=52.6%2C-4.4&output=xml
A snippet from what I'm trying from the playframework is the following:
val response = WS.url("http://www.myweather2.com/developer/forecast.ashx?uac=eDKGlpcBQN&query=52.6%2C-4.4&output=xml").get.get()
val body = response.getBody
When I call this, the body consists of "useraccount does not exist". When I just put this url in a browser, I get the response I'm looking for. What am I doing wrong here?
For some reason, I was getting WS from the wrong import. When I fixed the imports to import play.api.libs.ws.WS, it worked. I'm still amazed it worked halfway with the wrong import
Don't know about "useraccount does not exist" but this seems to work:
val promise = WS.url("http://www.myweather2.com/developer/forecast.ashx?uac=eDKGlpcBQN&query=52.6%2C-4.4&output=xml").get()
val body = promise.value.get.body
Edit: Removed the space.
Also make sure your editor is not inserting a \n or \r after ?
I know this is old, but I just solved this problem while trying to do the same thing - getting the same results.
GET variables must be passed with WS.url("http://...").setQueryParameter(key, value)
Example:
val promise = WS.url("http://www.myweather2.com/developer/forecast.ashx").setQueryParameter("uac", "eDKGlpcBQN").setQueryParameter("query", "52.6%2C-4.4").setQueryParameter("output", "xml").get()
Annoying, but a relatively simple fix.
