Given a tree-sitter tree for some HTML elements:
<script>console.log('should parse as js')</script>
<script async defer>console.log('works')</script>
(script_element
(start_tag
(tag_name))
(raw_text
; ... etc
)
(end_tag
(tag_name)))
(script_element
(start_tag
(tag_name)))
(attribute
(attribute_name))
(attribute
(attribute_name))
(raw_text
; ... etc
)
(end_tag
(tag_name)))
Broken Query
This query fails when used in neovim's tree-sitter html grammar injections.scm, returning an invalid field error
(script_element
(start_tag !attribute))
How would I query for <script> elements which do not have any attributes? Is it necessary for the grammar to assign a field name to the child in order for queries to negate it?
This was answered on GitHub discussions: https://github.com/nvim-treesitter/nvim-treesitter/discussions/2582
The gist of this answer is that you query for a script_element for which the tag name is the last child, so there are thus no other children such as attributes:
(script_element (start_tag (tag_name) .)) #foo

By default Ag Grid Quick Filter function return rows that contains search string. For example if I type "30 June" in the searchbox, quick filter will also return rows that contains "30 cars were sold by 2 June" text. How can I override default behavior to receive only rows that exactly match my search string?
What I did was the following:
In the search itself, I removed the spaces from the search criteria:
this.gridApi.setQuickFilter(event.toLowerCase().replace(" ", ""));
In each column that I wanted an exact match, I added this code in the column definition:
getQuickFilterText: (params) => { return params.value && params.value.toLowerCase().replace(" ", "");}
(That is the override method for search. See here for more details: https://www.ag-grid.com/angular-data-grid/filter-quick/)
It seems to be working for me.
To achieve the exact match results column wise, You have to do these two things :
Remove cacheQuickFilter property from your default column definition object in gridOptions as caching convert all the columns data into a string separated by backward slash. That's the reason it will not be able to search column by column.
Add getQuickFilterText function in each column definition and add a condition for a exact match else return an empty string.
getQuickFilterText: params => {
return (params.value === <quick filter value>) ? params.value : ''
}
Now the tricky part here is how to access quick filter value inside getQuickFilterText function. You can achieve this in two ways :
Assign an id to quick filter search element and then access it's value using document.getElementById('quick-filter').value
Store the quick filter search value on change and put into a store state or service and then access that inside getQuickFilterText function.
I have a postgres table in which I have some "defaulted" fields like date_created which automatically receives a current_timestamp as default.
or the ID field which gets it's value from a sequence defined in the database.
What would be (if possible) the syntax to tell the ORM module to not include these two fields when generating an INSERT statement ?
You can use a function as 2nd parameter to remove the fields:
$this->copyfrom('POST',function($val) {
unset($val['ID']);
unset($val['date_created']);
return $val
});
or to only copy allowed fields from the POST array:
$this->copyfrom('POST',function($val) {
return array_intersect_key($val, array_flip(array('name','age')));
});
Assuming you are using an HTML form to add new records into the tables, follow the steps below;
In the form, omit these 'defaulted' fields, i.e. add only the fields that you want to submit
Create a model with a function similar to below
public function add() {
$this->copyFrom ( 'POST' );
$this->save ();
}
Create a route that links the form to this function
I need to retrieve only part of a document and call it via a helper so that I can render a subtemplate multiple times as the part I require to pull from the db is an array of object itself. I have the following as the fields. What I need to do with my helper is only retrieve the ordersDispatch array of one particular document which would be uniquely called by the tripNumber field.
I have tried several things but nothing has come close to only having an array of the objects in the orderDisptach field be returned in a fashion that it can be used by the helper to render my subtemplate for each object in the array.
{
tripNumber: companyRecord.lastTripNum + 1,
custID: $('input:hidden[name=orderCustomerId]').val(),
custContact: $('input:text[name=customerContact]').val(),
custEmail: $('input:text[name=customerEmail]').val(),
trailerSealNum: $('input:text[name=trailerSealNum]').val(),
orderBroker: $('input:text[name=orderBroker]').val(),
orderEquipment: $('input:text[name=orderEquipment]').val(),
orderLoadNum: $('input:text[name=orderLoadNum]').val(),
orderPlacedDate: $('input:text[name=orderPlacedDate]').val(),
orderPrivateNotes: $('textarea[name=orderPrivateNotes]').val(),
orderPublicNotes: $('textarea[name=orderPublicNotes]').val(),
orderCurrency: $("input[name=orderCurrency]:checked").val(),
orderCharges: $('input:text[name=orderCharges]').val(),
orderFUELCheck: $('input:checkbox[name=orderFUELCheck]').is(':checked'),
orderFUELPerc: $('input:text[name=orderFUELPerc]').val(),
orderFUELTotal: $('input:text[name=orderFUELTotal]').val(),
orderGSTCheck: $('input:checkbox[name=orderGSTCheck]').is(':checked'),
orderGSTPerc: $('input:text[name=orderGSTPerc]').val(),
orderGSTTotal: $('input:text[name=orderGSTTotal]').val(),
orderPSTCheck: $('input:checkbox[name=orderPSTCheck]').is(':checked'),
orderPSTPerc: $('input:text[name=orderPSTPerc]').val(),
orderPSTTotal: $('input:text[name=orderPSTTotal]').val(),
orderTAXCheck: $('input:checkbox[name=orderTAXCheck]').is(':checked'),
orderTAXPerc: $('input:text[name=orderTAXPerc]').val(),
orderTAXTotal: $('input:text[name=orderTAXTotal]').val(),
orderTotalCharges: $('input:text[name=orderTotalCharges]').val(),
ordeBlockInvoicing: $('input:checkbox[name=ordeBlockInvoicing]').is(':checked'),
orderExtraCharges: orderExtraCharges,
orderPickups: puLocations,
orderDeliveries: delLocations,
orderDispatch: dispatchLocations,
createdDate: new Date(),
createdUser: currentUser.username
Any help in building a helper that will accomplish this would be greatly appreciated as I am new to meteor and mongo.
The following helper should give you what you need:
Template.oneTrip.helpers({
orderDispatch: function(tn){
return Trips.findOne({ tripNumber: tn }).orderDispatch;
}
});
Trips.findOne({ tripNumber: tn }) gets you an individual document and .orderDispatch returns the value of the orderDispatch key which in your case will be an array.
html:
<template name="oneTrip">
{{#each orderDispatch this._id}} <!-- assuming you've already set the data context to an individual order -->
{{this}} <!-- now the data context is an element of the orderDispatch array -->
{{/each}}
</template>
I am trying to insert a vertex with orientjs(previously oriento) query builder. My class has a link type property pointing to another class.
I know I can get it to work with a raw query string but I would love to use the query builder.
Here is what I've tried so far :
db.insert()
.into('VertexClassName')
.set({"prop":"value", "linkProperty":"33:1289287"})
db.insert()
.into('VertexClassName')
.set({"prop":"value", "linkProperty":"#33:1289287"})
I get the following error :
Error on saving record in cluster #13
Am I setting properties in the right way ?
Could the error be related to somtehing else ?
I have sucessfully ran an insert query in the cluster #13 with a raw query string in the studio...
According to the official documentation it seems that the problem might be at the end of your statement
db.insert().into('VertexClassName')
.set({"prop":"value", "linkProperty":"33:1289287"}).one()
.then(function (data) {
// callback
});
Check if your code works adding one() to the pipe line
EDITED: I found this method in orientjs.
db.create('VERTEX', 'V')
.set({
key: 'value',
foo: 'bar'
})
.one()
.then(function (vertex) {
console.log('created vertex', vertex);
});
When using Tinkerpop API they recommend using createVertex instead of insert, because createVertex is intended for graphs and insert for Documents... Could you try with the create() method instead?
I am using SQL and it worked.
sql = "INSERT INTO Station set linked = (select from LinkedClass where LinkedProb = 'value'), prop = 'value'"
OrientVertex vertex = new OrientVertex();
vertex = graph.command(new OCommandSQL(sql)).execute();
I don't think that's possible unless you've added a proper field with the right type 'Link' in your schema. (which I rarely do).
Now instead of having the right 'link' type inserted you can do the opposite, store is as a String, and leverage the query functions to use it correctly:
db.insert().into('table').set({prop: '#15:14'}).one();
And it will be converted as String (which is a bit sad) but then you can use that in your queries:
SELECT eval(prop) FROM table;
And it will be 'eval'-ed to a Node RecordID that you can directly use and call functions like expand() on.
For example:
SELECT name FROM (SELECT expand(eval(prop)) FROM table);
Will eval the node stored in the insert(), grab the node, expand it and collect its name property.
Can we have a condition clause in APEX form :
Value of Item / Column in Expression 1 = Expression 2,
where expression1 is a form variable like P19__ROW_last_update_ts and
the second expression2 is a sql query like select max(date_max) from table
Please help me on this.
You can do this by adding a property on your form controller that executes the query and returns the result. The property will look something like:
public String getExampleProperty {
get {
return [/*some query in here*/].someProperty;
}
}
And then in your form, you'll reference the value like:
{!exampleProperty}
Note that you don't use the 'get' prefix in your visual force markup.
Hope this helps!
