I look for info on :
what modulation is used by thes protocole
if more than one is used : in with case one is used
List of potocole and data i find:
bluetooth : V1=MSK / V2=DQPSK / low energy=GFSK(not sure)
wifi : PSK(hypothesis)
RFID : BPSK
Zigbee 868MHz: BPSK(not sure in if it's the only one)
domotic 868MHz : BPSK(hypothesis)
I'm trying to learn django but the instructor uses django 1.X.X.
So far, I've been able to update stuff to Django 3.X.X to get it working.
But I'm stuck now.
Specifically, in the below urlpatterns code:
urlpatterns = [
path('',views.SchoolListView.as_view(),name='list'),
path('<int:pk>/',views.SchoolDetailView.as_view(),name='detail')
]
The first path works. The second one doesn't.
When I click on the url nothing happens. No error code, nothing.
I think there is a problem with the syntax? Is it different for Django3?
I checked the documentation and couldn't find anything wrong.
Thank you.
For example:
path ('',views.index , name='index')
For your code:
path('',views.SchoolListView,name='list')
The second pattern is part of djangos generic view .Generic views abstract common patterns to the point where you don’t even need to write Python code to write an app.
path('<int:pk>/',views.SchoolDetailView.as_view(),name='detail')
Here pk represents primary key. Check if you have data with primary key you are giving in database.
Alternatively if u dont want to use generic method, you can use this
path('<int:school_id>/‘, views. SchoolListView, name='schoollist')
, where school_id(it can be other name depending on your model, verify it in db) should be the primary key in database created by django.
I ' ve some troubles , managing my i18n in my database
For now I ' just two languages available on my application , but in order to be scalable, I would like to do it the "best" way.
I could have duplicated all fields like description_fr, description_en but I was no confortable with this at all. What I've done for now, is a external table , call it content, and its architecture is like this :
id_ref => entity referenced id (2)
type => table name (university)
field => field of the specific table (description)
lang => which lang (fr, en, es…)
content => and finally the appropriate content.
I think it can be important to precise, I use sequelizeJS as ORM. So I can use a usefull hooks as afterFind, afterCreate and afterUpdate. So Each time I wanna to find a resource for example, after find it, my hook retrieve all content for this resource and set definitly my object with goods values. It works, but I'm not in love with this.
But I have some troubles with this :
It's increase considerably my number of requests to the database : If I select 50 rows for example, I have to do 50 requests more.. , and just for a particular model. If I have nested models, it's exponential…
Then, It's complicated to fetch data by content i18ned. Example find a university with a specific name is complicated.
And It's a lot of work for updating etc...
So I wonder, if it would be a good idea , to save as a JSON, directly in the table concerned , the data. Something like
{
fr : { 'name':'Ma super université' },
en : { 'name':'My kick ass university' }
}
And keep on using Sequelize Hooks to build and insert proper data into my object.
What do you think ?
How do you manage this ?
EDIT
I use a mysql database
It concerns around 20 fields (cross models)
I have to set the default value using a my default_lang if there is no content set (e.g, event.description in french will be the same as the english one, if there is no content set)
I used this npm package sequelize-i18n. It worked pretty fine for me using sequelize 3.23.2, unfortunately it seems does not have support for sequelize 4.x yet.
Just wondering if anyone could enlighten me to what sth might be. (Seen in Tranalyzer flow files.) Basically it's a web analysis category (ip address, port, sth, etc) but I'm not sure what meant by it and there is no mention in the documentation.
(Also for bonus points what would a value of dir mean for sth?)
I'd appreciate any help.
sth means : STatement Handle
The connection to a database.
See http://perlmeme.org/tutorials/connect_to_db.html and https://stackoverflow.com/a/13208866/465183
Edit :
In perl, if I display the content of the object using Data::Dumper with a DBI script :
$VAR1 = bless( {}, 'DBI::st' );
but that's not very helpful. It's means only that's a DBI::st object.
I really don't know what's going on with my configuration, but I'm just not able to query anything after indexing (don't even know if I'm doing the indexing part correctly). Could someone please tell me what each of the following means and should be?
I have a CouchDB database called bestdb. Inside this database I have document types like product and customer.
Now I installed elastic search version 0.18.7 and the corresponding couchdb river. I started elastic search and couchdb. I set the network.host of elasticsearch to be an ip address: 10.0.0.129 . I followed the instructions in the tutorial :
curl -XPUT '10.0.0.129:9200/_river/{A}/_meta' -d '{
"type" : "couchdb",
"couchdb" : {
"host" : "localhost",
"port" : 5984,
"db" : "bestdb",
"filter": null
},
"index" : {
"index" : "{B}",
"type" : "{C}",
"bulk_size" : "100",
"bulk_timeout" : "10ms"
}
}'
{A}: What's this? My understanding is that this is just an internal elastic search index right? It's not being used for querying or searching right? So this could be any name right?
{B}: What's this index? How is this different from the one above? What should the value of this be in my scenario?
{C}: Is this related to the Document Type in couchdb, like product or customer ?
The online tutorial just sets everything to be the same value. How would my curl statement look like if I wanted to query all product documents or customer documents?
Thank you to whoever that clears things up a bit for me.

kimchy's documentation often leaves a little bit to the imagination. :-)
A is the river name. A river is just an ES document, stored in an index named _river, a type named whatever you want, and a doc id _meta.
B & C is the local index/_type that your bestdb couchdb _changes stream will get indexed into. These can be overridden by _index and _type fields in your couchdb documents. If none of the above is supplied, they'll default to your couchdb instance name bestdb/bestdb.
