This question is about Natural earth 1:10 states and provinces.shp file. I'm using ogr2ogr and want to know the name of the id i need to pass . In purpose of pulling out the right states regions to make a geojson file with it. I've use couple of properties name that didn't work (-where "adm0_a3 IN ('MLI')" \ , -where "iso_a2 = 'ML'" \ ).
I get those id from Let's make an map tutorial but they where referring to another shape file. Can anyone help me .
You could try with -sql variants, but I find the interface a bit oblique. In your shoes, I'd import the shapefile into a PostGIS table and then work from there. You get reliable querying and native support for GeoJSON export via ST_AsGeoJSON.

I have a lot of sub-collections within my main collection in Firestore. The sub collection names are like: image_1, image_2, 123_image_3 etc. Each of these sub-collections have documents with different fields. I want to export these to Cloud Storage.
Is there any way through which I can pass the sub collection names by using wildcards or anything else? I have more than 50 sub collections containing the string 'image' in their names and I cannot manually pass every name in my firestore export command.
command:
gcloud firestore export gs://bucket_name/image --collection-ids='%image%' this does not work.
The available option to export specific collections is by using the feature --collection-ids, which allows you to set specific collections and sub-collections to be exported - as indicated in the official documentation here.
Considering that, unfortunately, it's not possible to achieve what you are trying to do to. For this reason, I would recommend you to raise a Feature Request in Google's Issue Tracker, so they can check the possibility of implementing this in the future.
Let me know if the information helped you!
I am trying to save an array of text containing category types for a hotel system which looks something like this ['category-1', category-2', category-3, category-4] . I am using category_type = ArrayField(models.CharField(max_length=200),null=True) in my models.py
The error i get is
malformed array literal: "" LINE 1: ..., '{category-1,
category-2}'::varchar(200)[], ''::varcha...
^ DETAIL: Array value must start with "{" or dimension information.
The error persist even after processing python list from ['category-1', category-2', category-3, category-4] to {category-1, category-2, category-3, category-4}.
I have gone through postgresql documentation and have found very limited help,
https://pganalyze.com/docs/log-insights/app-errors/U114 this is something similar posted to what i am facing problem with.
Could someone please tell me what am i doing wrong? Any help would be appreciated.
EDIT:
Following is in my View.py
hotel_category=categoryTable(category_type=categorytype)
hotel_category.save()
and i am using categorytype=request.POST.getlist('category-type') in my Views.py to get it from the POST request after user submits the form. This returns a Python list that i have mentioned above, i have manipulated this list to match PostgreSQL ArrayField with '{','}' but i still have this error. If there is anything else you would like me to add, please let me know. :)
This is an update/answer to my question for anyone who faces this issue in the future. After struggling to find help from different resources, i decided to use JSON string to store my python list.
I am using :
categorytype = json.dumps(request.POST.getlist('category-type'))
to encode and using JSONDecoder() to fetch from database and decode. I have no idea how would this impact my further development but for now it seems a decent approach since personally i think ArrayFields are not well supported and documented in Django.
I will keep this post updated as i progress further on how this approach has impacted my development.
Have a nice day.
Trying get started with custom module development on Drupal 8. Don't have previous Drupal dev background. Been reading and watching some materials in the past 2 or so weeks.
I decided to dare doing a little more "complex" other than "Hello World", but I got stuck on how would I actually go about this.
This is what I have so far:
I created a content type for "people". It's very simple, all it has is the person's name and birthdate (date only), so you can use the form to input a few people.
I created a view that displays the list of people, their names and their birthdate. Of course everything so far is using the core admin thing.
Now, I wanted to create a custom module that calculates the person's age (based on the date stored in the DB). It takes today's date, subtracts the person's birthdate, and calculates their age.
Then, with some magic, it returns the age to the render/page output and now this calculated value (the age) will be displayed on the view as well along with the person's name and birthdate.
I assume I would need to "hook into" a place somewhere, where the list of people is returned from the database. Then I loop through the data, get the birthdate, calculate the age, stick the result (age) back into the data, and then the page/view will display this - somehow.
Of course I am already stuck on how would I go about doing this? Where would I need to hook into? With what API? And then of course, I created a view already, but the view doesn't have the "age" field - since that is calculated on the fly. So where and how would I display it?
So many questions...
If anyone would know some tutorial that is similar to this, I'd appreciate it. It's kinda tough getting started with the "custom" side of Drupal.
Thanks for some tips!
without custom programming
You can actually do this without custom coding. For this you can I would use either of the following modules field_token_value or computed_field.
They both create a field without giving the user a textbox to input any value.
The value of such fields are calculated from predefined rules/custom coding/tokens defined per field.
from your custom theme
The easiest way is to do this on the theming layer and not store this value in the database. You have to use hook_preprocess_node in your THEMENAME.theme
function THEMENAME_preprocess_node(&$variables){
//install debug and kint to be able to use
//kint($variables);
$node = $variables["node"];
if($node->getType() == "CONTENTTYPE" && $node->hasField('field_date')){
//get date value something like "2018-09-07T21:35:30"
$date = $node->field_date->value;
//your logic and age calculations
// ...
$age = 35;
//set variable to use in node.html.twig based templates
$variables["person_age"] = $age;
}
}
In order to get more information on what is available install debug module and enable kint (which is part of debug) to be able to see variables using kint function
Than copy node.html.twig from your custom theme (or parent theme or classy core theme) to your THEMENAME/templates folder and rename it node--CONTENTTYPE.html.twig.
In there you can include the variable you just created in proprocess.
person age: {{ person_age }}
Make sure you clear the cache for all those changes to be seen by Drupal.
FOR MORE INFO
To find out what twig templates to override see here
More on twig and getting available variables
Getting more info on which twig template is used can also be obtained by enabling debug mode on previous link.
I would suggest you pick up a book on drupal development to understand all those concepts in a more concrete way.
I would like to have "realtime" like map.
My main question is:
How to use django-olwidget with openlayers OpenLayers.Strategy.Refresh?
Do I need to start back "from scratch" to use manually openlayers?
With django-olwidget, the data is on the web page so the args which define data-source, protocol.
My "second" question is about which format should I choose...
geoJSON? kml? other?
Can those formats contain openlayers point specific "style" specifications like:
{'graphic_name': 'square', 'point_radius': 10, 'fill_color': "#ABBAAB', 'stroke_color':'#BAABBA'}.
I already overriden the default map template olwidget/multi_layer_map.html to access my map object in JS. I think it should be rather simple to apply a js function on each data layers before passing it to the map.
Thanx in advance.
PS: I'm french speaker.
PS2: I asked this question as a feature request on github: https://github.com/yourcelf/olwidget/issues/89
If you're going to use regularly-refreshing data (without refreshing the page) and serialization formats like geoJSON and KML, django-olwidget won't help you very much out of the box. You might find it easier just to use OpenLayers from scratch.
But if you really wanted to use django-olwidget, here's what I would do:
Subclass olwidget.InfoLayer to create a new vector layer type that uses a network-native format like geoJSON or KML to acquire its data.
Add a corresponding python subclass to be able to use it with Django forms or whatever the use case is. You'll probably need to specify things like the URL from which the map will poll its data.
This is a lot of work beyond writing for OpenLayers directly. The advantages would be that you would get easy Django form integration with the same map.
As to which serialization format to use: I'm partial to JSON flavors over XML flavors such as KML, but it really doesn't matter much -- Django and OpenLayers both speak both fluently.
About the styling,you should take a look at the StyleMap[1] where you can set style properties according to attributes.
For the main question, I’m sorry I don’t know django-olwidget…

Is it possible to create and/or edit MS Word and Word Perfect documents with django? I'd like to be able to allow the user to fill out a form and have the form fields inserted into an MS Word/Word Perfect document. Or, the form fields are used to create a new MS Word/Word Perfect document. The user can then send that document via email to others who may not have access to the django web-app.
I have a client who needs this functionality and I'd like to keep it all within the web-app.
Any ideas?
Thanks!
For MS Word, you could use docx-mailmerge. Run the following commands to install lxml(dependecy required by docx-mailmerge) and docx-mailmerge
conda install lxml
pip install docx-mailmerge
In order for docx-mailmerge to work correctly, you need to create a standard Word document and define the appropriate merge fields. The examples below are for Word 2010. Other versions of Word should be similar. It actually took me a while to figure out this process but once you do it a couple of times, it is pretty simple.
Start Word and create the basic document structure. Then place the cursor in the location where the merged data should be inserted and choose Insert -> Quick Parts -> Field..:
Word Quick Parts
From the Field dialog box, select the “MergeField” option from the Field Names list. In the Field Name, enter the name you want for the field. In this case, we are using Business Name.
Word Add Field
Once you click ok, you should see something like this: <> in the Word document. You can go ahead and create the document with all the needed fields.
from __future__ import print_function
from mailmerge import MailMerge
from datetime import date
template = "Practical-Business-Python.docx"
document = MailMerge(template)
document.merge(
status='Gold',
city='Springfield',
phone_number='800-555-5555',
Business='Cool Shoes',
zip='55555',
purchases='$500,000',
shipping_limit='$500',
state='MO',
address='1234 Main Street',
date='{:%d-%b-%Y}'.format(date.today()),
discount='5%',
recipient='Mr. Jones')
document.write('test-output.docx')

I do not know how to do exactly what you ask for, but I would suggest that you also look into creating PDFs with Django. If you only want to send information in a particular format then PFD might be better because it is more portable across platforms. You may also want to look at this documentation for how to send emails from Django.
