Let say you are using the Simple schema package for meteor, and you want to have a property that will store text content for a CMS and you don't know how much text the user will use, what would be a good number for the max property in the simple schema?, and what would happen if I don't set the max property?, could I run into the problem of someone sending 1 MB of text? Would be a better idea to use a custom validation to calculate the size of the text?
myCMSSchema = new SimpleSchema({
textContent : {
type : String,
max : 150 //<--- max?
}
});
For string values, max defines the maximum string length. You can set a reasonable length there.

Using Ionic 2, I am unsuccessfully trying to retrieve and display the newGoalWt, newMaxReps, newMinReps, repsToday, and wtToday shown at the bottom of the firebase data image. I do not want to retrieve the other data. I thought I found the answer to this several times, but I haven't. I am not trying to get others to do work I should be doing but I am new to coding and need help at this point. If you have another course that covers this by example please let me know. sample database
I hope this makes sense/is clear.
First thing is to create a provider which gets the details. So in the provider there will be a function like this :
public getRequiredObject(objectKey : String){
return this.database.object('wideGripBPTwo-list/'+ objectKey)
}
Then in the controller/typescript file i would have a variable assigned to the return value of the provider :
this.variableName = this.Provider.getRequiredObject(objectKey);
this.variableName.subscribe(snapshot => {
this.newGoalWt = snapshot.newGoalWt;
this.newMaxReps = snapshot.newMaxReps;
//add other variables here
Lastly in the html file just bind the data :
<ion-label>{{newGoalWt}}</ion-label>
Note I have not added entire provider, .ts file and html file.
Please advise if this makes sense and if you need more assistance.
I need to fetch from BaaS data store all records that doesn't match condition
I use query string like:
https://api.usergrid.com/<org>/<app>/<collection>?ql=location within 10 of 30.494697,50.463509 and Partnership eq 'Reject'
that works right (i don't url encode string after ql).
But any attempt to put "not" in this query cause "The query cannot be parsed".
Also i try to use <>, !=, NE, and some variation of "not"
How to configure query to fetch all records in the range but Partnership NOT Equal 'Reject' ?
Not operations are supported, but are not performant because it requires a full scan. When coupled with a geolocation call, it could be quite slow. We are working on improving this in the Usergrid core.
Having said that, in general, it is much better to inverse the call if possible. For example, instead of adding the property when the case is true, always write the property to every new entity (even when false), then edit the property when the case is true.
Instead of doing this:
POST
{
'name':'fred'
}
PUT
{
'name':'fred'
'had_cactus_cooler':true
}
Do this:
POST
{
'name':'fred'
'had_cactus_cooler':'no'
}
PUT
{
'name':'fred'
'had_cactus_cooler':'yes'
}
In general, try to put your data in the way you want to get it out. Since you know upfront that you want to query on whether this property exists, simply add it, but with a negative value. The update it when the condition becomes true.
You should be able to use this syntax:
https://api.usergrid.com/<org>/<app>/<collection>?ql=location within 10 of 30.494697,50.463509 and not Partnership eq 'Reject'
Notice that the not operator comes before the expression (as indicated in the docs).
I use dojo.grid.datagrid
If the DataGrid contains lots of rows(example 200) and to scroll, it does not work exit from edit mode cell. Do know what the problem is?
upd: Or maybe someone knows how to use dgrid / gridx in xPages, becouse i found next big bug - encoding after save rest service :(
I just did some testing and I believe I'm seeing the same thing. It seems to be fine to edit and save as I move through the grid. I can scroll down as needed and save changes. However, when I scroll back up and put a cell in edit mode, it doesn't save the changes -- it immediately reverts to the original value. And sometimes it just leaves the cell in edit mode.
I would agree that it seems to be an issue with memory management. If I set the rowsPerPage to a number that will keep all rows in memory, it appears (with very limited testing) that I can scroll up and down and make changes and they're all saved.
I don't have a solution at the moment, but what I would suggest in lieu of a perfect solution is to find a way to set rowsPerPage to a number greater than the amount of rows that will be displayed in the grid. If there's too much data for that to be feasible, then the approach I would take is to provide filtering on the grid to keep the maximum number of rows displayed much lower and then it won't be as much of a performance hit to set the rowsPerPage to a sufficient amount.
If I come across a better solution, I'll come back and post it here.
Yeah! I solved it! :) Error in FileStore.js(extlib). Add this on onClientLoad. I change "!!error code"
restViewItemFileService._processResponse = function(requestObject, data) {
this._items.splice(0, this._items.length); // !!error code -> this.close();
this._start = requestObject.start;
//TODO: clear identity?
dojo.forEach(data.items, function(entry, idx) {
var item = {storeRef:this, attributes:entry};
var id = item.attributes[this._identity]
var pending = this._pendings[id]
if(pending) {
for (var s in pending.modAttrs[s]) {
this.item.attributes[s] = pending.modAttrs[s]
}
}
this._byIdentity[id] = item;
this._items.push(item);
}, this);
this._topLevelEntries = data['#toplevelentries'];
this.onData(requestObject, data);
this._finishResponse(requestObject);
}
How do you set the limit on the length of a POST request in twisted? I've looked around in the docs and can't find anything. It would even help if I knew the default limit.
I don't believe there is a default limit on the size of incoming POST data, but you could pretty easily impose one by overriding the Request.handleContentChunk() method, with something like:
from twisted.web import server
class SizeLimitingRequest(server.Request):
def handleContentChunk(self, data):
if self.content.tell() + len(data) > self.size_limit_on_post_data:
raise SomeKindOfError("too much data nooooooo")
return server.Request.handleContentChunk(self, data)
the actual method you'd be overriding is in twisted.web.http.Request, which is a superclass of server.Request. To make use of your shiny new class, just set your Site instance's requestFactory attribute:
mysite.requestFactory = SizeLimitingRequest
I am designing an infopath (Change Request) form:
1)How can i add a text box that automaticaly increments to the next number when a new form is created (adding a new Change Request form to the form library).
2)How do i retrieve information from an existing form to the new form.
NOTE: The field is not inside a repeating table. I need to generate the next Change Request number on each new Change Request form.
TIA!
There is no build-in way to do this, but there are several ways to achieve what you want (Database query or SPList query). But this kind of request somehow smells like a workaround for an other problem.
Common cases for increasing numbers are:
unique IDs
count the Requests
make referable by external list (same as ID)
make IDs guessable (time stamps are not)
If you need an ID: In most cases you are not forced to use integer IDs. Simply use the form title as a natural ID. (e.g. customer + timestamp)
If you need guessable IDs, you need them because an external system wants to access or refer to the request. In that case try to change the pull-direction into a push-direction (e.g. by using workflows) or let your other system provide a "getID" function that can be called by your form to obtain a known ID (no guessing needed).
Anyway - for me, it looks like you want to achieve this to solve some other problem. Maybe there are different solutions for that problem too?
You could enter a token in your text-titles on the form where you want autonumbering, such as #num#, and then use javascript or jquery to find those tokens and replace them with incremented numbers.
The drawback to this is that if you exported the list to excel, the tokens would not get translated to numbers. But it is a good solution for on-screen rendering.
Use Firebug to figure out the class of the container housing your autonumber tags.
Maybe you could do something like this:
function TokenReplacement(){
var ClassName = 'ms-formlabel';
var elements = new Array();
var elements = document.getElementsByTagName('td');
var numerator=0;
//Now do find and replace on everything else
for(var e=0;e<elements.length;e++){
thiselement = elements[e];
if(thiselement.className == ClassName){
//autonumber the questions by replacing the #num# token
if(thiselement.innerHTML.search('#num#') > -1){
numerator++
var replacenum = "<b>" + numerator + ". </b>";
thiselement.innerHTML = elements[e].innerHTML.replace('#num#',replacenum);
}
}
}
}
