For a number of reasons my blog has been having something of a rest, but I have been busy in a number of fields and I will be posting about those shortly.

When working with Cloudflare Workers you sometimes need to use a feature which Cloudflare calls “Secrets” .
To create a “Secret” called “FOO” you do this …
$ wrangler secret put FOO
… and you’ll get prompted for what value you want to associate with ‘FOO’.
The strange thing is that if you go into your Cloudflare dashboard there’s no sign of any “Secret”.
After a good deal of digging around I found the “Secret” I had created but it’s not referred to as “Secret” it’s labelled “Environment Variables”. That’s actually a better name for it than “Secret” but it’s pretty confusing and there’s no reference that I can find for it in the Cloudflare documentation.
So just to be clear this is how you find your “Secret” …
When developing Cloudflare Workers which make use of Cloudflare KV there’s an error message you might get which reads like this :
Error: In order to preview a worker with KV namespaces, you must designate a preview_id in your configuration file for each KV namespace you'd like to preview.
There’s a couple of things it’s useful to know when resolving this, and as far as I can see it’s not clearly documented in the Cloudflare Workers, or KV documentation.
If you’re seeing this you need to go and inspect your wrangler.toml file. You probably have something that looks like this :
kv_namespaces = [
{ binding = "FOO", id = "bb12cc34dd56eebb12cc34dd56eebb12" }
]
Or you may have no kv_name_spaces entry at all. Either way this is how to resolve the situation.
Execute the following command.
$ wrangler kv:namespace create "FOO" --preview
If you do have an existing entry for kv_namespaces be sure to use the binding property value that’s already in use, in this example ‘FOO’, otherwise use whatever name you want as your namespace name.
Once you’ve executed that command you should see output which looks like the following :
Add the following to your configuration file in your kv_namespaces array:{ binding = "FOO", preview_id = "d94ab232f1ef23acdeaeef0add746a48", id = "bb12cc34dd56eebb12cc34dd56eebb12" }
Go ahead and place that in the wrangler.toml and you should find the …
Error: In order to preview a worker with KV namespaces, you must designate a preview_id in your configuration file for each KV namespace you'd like to preview.
… message doesn’t appear any longer when using wrangler dev or wrangler preview.
The Fake library has a whole lot of built in properties that you can use to generate fake data for testing, etc. Unfortunately the documentation hasn’t kept up with the available properties so here’s a list of most of them as they are in the current release. It’s ‘most of them’ because some properties, such as ‘tar’, don’t lend themselves to easily being on a web page.
Once I get some time I’ll do a pull request for the documentation for the actual project so that this page will become redundant.

When using the behave framework for functional testing it’s often necessary to set some data at the start of the testing and be able to make use of it throughout the test run.
The context object (api of the object) is there to help you however I don’t think the current documentation makes it as it clear as it should be how you do this.
Within the environment.py (placed in your features directory) you can define an event handler to run before any testing is done, that event handler is called before_all below is an example of using before_all to set an arbitrary value which is then available through out the test run.
#This event runs before any of your tests
def before_all(context):
#Choose whatever property name you like and assign
#a value to it. In this case I have chosen 'colour'
#and assigned "RED" to it.
context.colour = "RED"
#You can assign any python object to one of these
#properties, here's an example of assigning a dictionary
#to one
context.weather = {'temp-centigrade': '21', 'wind-speed-kmh': 5}
The context object is used by behave for other purposes so whatever property you set you need to check that it’s not one that is used by behave internally.
There’s a list of the internally used properties here so you can avoid them.
To ensure you don’t accidentally stomp on one of the predefined properties it might be best to use only one top level property (eg context.my_project_name) and assign an empty dictionary to that. You can then store everything you want within the dictionary at context.my_project_name).
I’ve taken to using pipenv (“Python Development Workflow for Humans”) recently and so I frequently come across things I haven’t done previously and need to figure out how to. Todays’s is using pipenv to install a package from a github repository.
So, short and sweet, here’s how. In my case I have forked the repos ‘behave-web-api‘ and I want to install my forked version into my current project.
$ pipenv install -e git+ssh://git@github.com/shearichard/behave-web-api.git#egg=behave-web-api
Notice the git+ssh is used as the scheme of the url. Also notice that the egg=behave-web-api (with the value after the equals sign changed to whatever package you’re dealing with) is necessary .

The pipenv doco for this is comprehensive but because it’s so comprehensive is a little more than you might need in a lot of cases. I also found the note written to himself by Koen Woortman a useful pointer.
As a reminder to me, and I hope, a help to others here are the various ways in which JavaScript arrow functions can be used to reduce the amount of code you write.
Here I start with an old fashioned JavaScript function being used as an argument to the map function and then step by step reduce the amount of the code to take full advantage of the possibilities of JavaScript arrow functions. Not all of these steps would be possible in all circumstances.
//Test data is an array of integers
const nums = [1,2,3,4,5,6,7,8,9,10]
//We start by using a 'traditional'
//function definition as our argument
//to 'map'
const first_approach = nums.map(
function(n){
return num * 2
}
)
//Convert the 'traditional' function
//definition to an arrow function
const second_approach = nums.map((n) => {
return n * 2
})
//When there's only one argument to the
//function we can remove the brackets
//around the argument, so 'n' is no
//longer bracketed
const third_approach = nums.map(n => {
return n * 2
})
//Because only one thing is being
//returned the processing can all be
//placed on one line ...
const fourth_approach = nums.map(n => { return n * 2 })
//Take advantage of the implicit return
//within an arrow function so we no longer
//need to use 'return' and, in the process,
//do away with the curly brackets.
const fifth_approach = nums.map(n => n * 2 )

So just to summarise, in the right circumstances it’s possible to go from this …
//Longest version
const first_approach = nums.map(
function(n){
return num * 2
}
)
… to this .
//Shortest version
const fifth_approach = nums.map(n => n * 2 )
Fuller details about when all of these optimisations are possible are available on the excellent MDN Arrow Function page.
I just had a VirtualBox client machine start but the window it was running in was blank. I fiddled around for a while and then waited. Still nothing in the client machine window but blackness.
I looked at the logs held by VirtualBox and there was nothing that looked unusual, although there’s a lot in those logs and I never normally read them so plenty of scope for overlooking something significant.
Then I tried to ssh into the client machine, fully expecting this to fail. It worked!
Then I found this web page and it mentioned Display Memory. Well I knew the display memory had been good the last time I used the VM so I couldn’t see how that was a problem ? But in fact when I went into settings I discovered the Display Memory had been changed to 1MB. My sticky fingers at work I guess ? Regardless I gave it 128MB and closed down the machine through the SSH session, then restarted and, bang !, the machine’s display was back working as it should have been.
Long story short if your Virtualbox machine is blank go and check the Display Memory settings.
Today I’ve started my first django-sockpuppet project ( https://pypi.org/project/django-sockpuppet/ ).
If you’re using pipenv the first thing you need to do is
pipenv install django-sockpuppet
but I found that command failed when it came to installing the dependency on Twisted https://pypi.org/project/Twisted/ .
The problem was that I had started using a new virtual machine for development and it was lacking libraries which Twisted depends on. To be clear this is an Ubuntu 20.x machine and this problem may be specific to that environment.
So if you’re using django-sockpuppet and you have problems installing it try executing the following.
sudo apt-get install python3-dev sudo apt-get install libevent-dev
This is pretty standard stuff for a new machine but easy to forget if you don’t change very often.
This is going to be of interest if you’re using the ember-cli-jstree addon and you want to programmatically open a node in the tree. It’s niche, but if you want it … here it is.
If you want a tree widget as part of your interface then the jsTree jquery plugin is a good option. I’ve used it on a number of projects and while it’s not perfect it’s really very good.
If you’re working with Ember.js then an ember addon, ember-cli-jstree, exists to allow you to use the jsTree plugin in a more “emberish” manner.
So for our current purposes I’m going to assume you’ve
Looking at the documentation, here and here , it seems that all that’s needed is to specify the node you want to open but I’ve found that’s not so.
In fact if you want to open a node other than the topmost node it’s necessary to make a series of calls to open_node starting at the topmost node and ‘walking’ down to the node you wish to open.
So imagine you have a tree which shows areas of the United States and that you wish to open a node that corresponds to the street in New York City called Broadway.
On first reading it would seem that all that was necessary was to execute the following, but that’s not so.
this.myActionReceiver.send('openNode', 'Broadway');
In fact to do that it would be necessary to execute the following processing
this.myActionReceiver.send('openNode', 'NY');
this.myActionReceiver.send('openNode', 'NewYorkCity');
this.myActionReceiver.send('openNode', 'Manhattan');
this.myActionReceiver.send('openNode', 'Broadway');
If you find yourself having do this then it’s worth remembering that the parameters passed to a number of events include a action object and within the action object there is an array of parents which in the above example would look like this.
# action.node.parents
["Manhattan", "NewYorkCity", "NY", "#"]
Hope it was helpful.
