I have a function, and in this function I have:
this.geolocation.getCurrentPosition(posOptions).then((localisation,err) => {
this.storage.get('param1').then((param1) => {
this.storage.get('param2').then((param2) => {
// Do some stuff with localisation, param1 & param2
alert(localisation);
alert(param1);
alert(param2);
})
})
})
That's the only way i found to use "localisation", "param1" & "param2" in the same time, if i do something like:
this.geolocation.getCurrentPosition(posOptions).then((localisation,err) => {
})
this.storage.get('param1').then((param1) => {
})
this.storage.get('param2').then((param2) => {
// Do some stuff with localisation, param1 & param2
alert(localisation);
alert(param1);
alert(param2);
})
It will not find localisation and param1
You can use promise.all here since the params are not interdependant. Promise.all takes in an array of promises and waits till all the promises return before executing the then.
let lPromise =this.geolocation.getCurrentPosition(posOptions);
let p1Promise = this.storage.get('param1');
let p2Promise = this.storage.get('param2');
Promise.all([lPromise,p1Promise,p2Promise])
.then((values) => {
// Do some stuff with localisation, param1 & param2
alert(values[0]);//localization
alert(values[1]);//param1
alert(values[2]);//param2
})

I'm trying to create a simple todo app, this is an input component and I need a reducer to update the state of the input. This code is throwing the error - This pattern matches values of type action but a pattern was expected which matches values of type unit => string
For some reason it expects action to be unit => string and I have no idea why. Can anyone help?
type state = string;
type action =
| InputChange(string);
let component = ReasonReact.reducerComponent("Input");
let make = (~onSubmit, _children) => {
...component,
initialState: () => "",
reducer: action =>
switch (action) {
| InputChange(text) => ReasonReact.Update(text)
},
render: ({state: todo, send}) =>
<input
className="input"
value=todo
type_="text"
placeholder="What do you want todo"
onChange={e => send(ReactEvent.Form.target(e)##value)}
onKeyDown={
e =>
if (ReactEvent.Keyboard.key(e) == "Enter") {
onSubmit(todo);
send(() => "");
}
}
/>,
};
The type of action is inferred by the use of send in render, where you pass it () => "", a function of type unit => string. It should be send(InputChange("")).
You're also missing the state argument on reducer. It should be reducer: (action, state) => ..., or reducer: (action, _state) => ... to avoid the unused warning, since you're not using it.
I'm trying to cleanup 2 collections before each test. I'm using mocha --watch to rerun tests while editing the test source files. First run always executes as expected, but consecutive runs gives Topology was destroyed error from mongodb(indicated via result of http request).
I am not really sure why deleteMany deletes my inserted object in consecutive runs.
describe('myCollection1 related tests', () => {
// myCollection1 documents should refer to a valid myCollection2 document.
var foo;
const exampleObject = {name: 'TEST OBJECT', attr1: 'TO'};
beforeEach(() => {
return Promise.all([
mongo.db('mydb').collection('myCollection1').deleteMany({}), // clear collection 1
mongo.db('mydb').collection('myCollection2').deleteMany({}) // clear collection 2
.then(() => mongo.db('mydb').collection('myCollection2').insertOne(exampleObject) // and add a sample object
.then((value) => {
foo = value.ops[0]; // save this as test specific variable so I can use it in my tests.
return Promise.resolve();
})),
]);
});
it('should create a related object', (done) => {
chai.request(server)
.post('/api/v1/foos/')
.send({ related: foo._id })
.then((res) => {
res.should.have.status(200);
res.body.should.be.an('object').with.all.keys('status', 'errors', 'data');
done();
}).catch((err) => {
done(err);
});
});
});
I spotted issue with your promise structure in beforeEach. I'm not sure it is intended or not. I'm afraid it is the culprit. I'm fixing that into below:
beforeEach(() => {
return Promise.all([
mongo.db('mydb').collection('myCollection1').deleteMany({}),
mongo.db('mydb').collection('myCollection2').deleteMany({})
]) // close the promise.all here
.then(() => collections.engines().insertOne(exampleObject)) // close `then` here
.then((value) => {
foo = value.ops[0];
return Promise.resolve();
});
});
Hope it helps
I have a search form for searching "documents", that have a small dozen of search criterions, including "entire_text", "keywords" and "description".
I'm using pg_search_scope, but I have 2 different scopes.
This is in my document.rb:
pg_search_scope :search_entire_text,
:against => :entire_text,
:using => {
:tsearch => {
:prefix => true,
:dictionary => "french"
}
}
pg_search_scope :search_keywords,
:associated_against => {
:keywords => [:keyword]
},
:using => {
:tsearch => {
:any_word => true
}
}
Each separately works fine. But I can't do this:
#resultats = Document.search_keywords(params[:ch_document][:keywords]).search_entire_text(params[:ch_document][:entire_text])
Is there any way to work around this?
Thanks
I've never used pg_search_scope but it looks like you indeed can't combine two pg_search_scope's.
What you could do is use :search_entire_text with a pg_search_scope and use the resulting id's in a Document.where([1,2,3]) that way you can use standard rails scope's for the remaining keyword searches.
Example:
# If pluck doesn't work you can also use map(&:id)
txt_res_ids = Document.search_entire_text(params[:ch_document][:entire_text]).pluck(:id)
final_results = Document.where(id: txt_res_ids).some_keyword_scope.all
It works. Here's the entire code ... if ever this could help someone :
Acte.rb (I didn't translate to english, the explanations are commented to correspond to the question above)
pg_search_scope :cherche_texte_complet, #i.e. find entire text
:against => :texte_complet,
:using => {
:tsearch => {
:prefix => true,
:dictionary => "french"
}
}
pg_search_scope :cherche_mots_clefs, #find keywords
:associated_against => {
:motclefs => [:motcle]
},
:using => {
:tsearch => {
:any_word => true
}
}
def self.cherche_date(debut, fin) #find date between
where("acte_date BETWEEN :date_debut AND :date_fin", {date_debut: debut, date_fin: fin})
end
def self.cherche_mots(mots)
if mots.present? #the if ... else is necessary, see controller.rb
cherche_mots_clefs(mots)
else
order("id DESC")
end
end
def self.ids_texte_compl(ids)
if ids.any?
where("id = any (array #{ids})")
else
where("id IS NOT NULL")
end
end
and actes_controller.rb
ids = Acte.cherche_texte_complet(params[:ch_acte][:texte_complet]).pluck(:id)
#resultats = Acte.cherche_date(params[:ch_acte][:date_debut],params[:ch_acte][:date_fin])
.ids_texte_compl(ids)
.cherche_mots(params[:ch_acte][:mots])
Thanks !

I am building a scheduling app. I am able to sort the database using the CJuiDatePicker widget's "onSelect" option. Now I am trying to use the "beforeShow" option to ensure that only dates that have tasks can be selectable. Can anyone help?
$this->widget('zii.widgets.jui.CJuiDatePicker', array(
'model'=>$dataProvider,
'attribute'=>'start_time',
'options'=>array(
'dateFormat' => 'yy-mm-dd',
'changeMonth' => true,
'changeYear' => true,
'beforeShowDay' => 'js:$.datepicker.noWeekends',
'beforeShow' => "js:function Check_Alert2(){
Check_Alert();
}
",
'onSelect' => "js:function SearchFunc() {
var data = $('input').serialize();
var url = document.URL;
var params = $.param(data);
url = url.substr(0, url.indexOf('?'));
window.History.pushState(null, document.title,$.param.querystring(url, data));
}"
),
'htmlOptions'=>array(
'style'=>'height:20px;',
'readonly' =>true,
),
));
i am still using the original code. I need an array generated within the beforeshowday. When i run your code it fails on the getdates() function call.
'beforeShowDay' => 'js:function(date){
var array = ["2013-10-30","2013-10-31","2013-12-18","2013-12-25"];
var string = jQuery.datepicker.formatDate("yy-mm-dd", date);
if (array.indexOf(string) == -1){
return [false,"", "No event"];
} else return [true,"", "Event"];
I wrote a filter like this in perl
my $tf = HTML::TagFilter->new(
allow => {
img => { src => [] },
b => { all => [] },
i => { all => [] },
em => { all => [] },
u => { all => [] },
s => { all => [] }
}
);
$message_body = $tf->filter($message_body);
now what I needed from this filter to do is allowing the given tags, and for img to allow the src attribute. The code gives great results except for tag like this <img src="cid:img.png" alt="Smiley face"> it just return <img> instead of <img src="sid:imp.png"> which is what I want, does any one here knows why?!
The reason your src attribute isn't being passed through is because of the module's cross-site scripting protection. The value cid:img.png is rejected as an invalid URL, and so the attribute is removed.
The tidiest way to get around this is to extend the list of valid protocols to include cid, like this:
my #protocols = $tf->xss_permitted_protocols;
push #protocols, 'cid';
$tf->xss_permitted_protocols(#protocols);
$message_body = $tf->filter($message_body);
If you set log_rejects => 1 when you create the HTML::TagFilter object then you can examine the values returned by $tf->report to see the module's reasons for rejecting each component of the HTML.
You need to set skip_xss_protection to 1:
#!/usr/bin/perl
use strict;
use warnings;
use HTML::TagFilter;
my $tf = HTML::TagFilter->new(
allow => {
img => {src => []},
b => { all => [] },
i => { all => [] },
em => { all => [] },
u => { all => [] },
s => { all => [] }
},
skip_xss_protection => 1,
);
my $html = qq{<img src="cid:img.png" alt="Smiley face">};
$html = $tf->filter($html);
print $html;
prints:
<img src="cid:img.png">
