Am new to couchdb2.0,working on map function.I have written a function
function(doc) {
if(doc.entityType!=null){
if(doc.cityName!=null && doc.locationName!=null){
var key =[doc.cityName,doc.locationName,doc.entityType]
emit(key, doc);
}
}
}
which is throwing
{"error":"compilation_error","reason":"Expression does not eval to a function. >>(function(doc) {\n if(doc.cityName!=null && doc.entityType!=null){key=>>[doc.cityName,doc.entityType] emit(key, doc);\n}})"}
Please help me out.
Add a semicolon to the end of the key variable instantiation:
var key =[doc.cityName,doc.locationName,doc.entityType];

I'm using the following script to pull data from bulk json files:
function importRegex(url, regexInput) {
var output = '';
var fetchedUrl = UrlFetchApp.fetch(url, {muteHttpExceptions: true});
if (fetchedUrl) {
var html = fetchedUrl.getContentText();
if (html.length && regexInput.length) {
output = html.match(new RegExp(regexInput, 'i'))[1];
}
}
// Grace period to not overload
Utilities.sleep(1000);
return output;
}
Then this formula with the desired URL in E3:
=IMPORTREGEX(E3,"(.*')")
It worked completely fine to begin with, now I'm suddenly getting the error, seemingly without making any changes, any tips?
This error is because of lacking a null check.
You are now using the return value of html.match() whether it is null or not.
So you should check if the return value is null and if it has enough length.
Like this:
if (html.length && regexInput.length) {
let match = html.match(new RegExp(regexInput, 'i'));
if ( match != null && match.length > 1 ){
output = match[1];
}
}
I would like to execute a loop in REPL mode but I am getting a SyntaxError: expecting '('
var methods = eval(ObjC.classes.UIViewController.$methods);
for item in methods { console.log(item) }
Here is an example for iterating and invoking class methods
var UIDevice = ObjC.classes.UIDevice.currentDevice();
UIDevice.$ownMethods
.filter(function(method) {
return method.indexOf(':') == -1 /* filter out methods with parameters */
&& method.indexOf('+') == -1 /* filter out public methods */
})
.forEach(function(method) {
console.log(method, ':', UIDevice[method]())
})
Update:
var UIViewControllerInstance = ObjC.chooseSync(ObjC.classes.UIViewController)[0];
console.log('Sanity check =', UIViewControllerInstance, JSON.stringify(UIViewControllerInstance.$ownMethods, null, 2));
UIViewControllerInstance.$ownMethods
.filter(method => { return method.indexOf(':') == -1 && method.indexOf('+') == -1 })
.forEach(method => {
console.log(method, ':', UIViewControllerInstance[method]())
})
Instead of looking for UIViewController instances on the heap, you have direct access through UIApplication
take a look # https://frida.re/docs/examples/ios/
This problem is related to command line shells and not to Frida or any other REPL tool.
This is a Single command and multiple lines subject of a shell in terminals.
To solve it, all you need to do is to add "\" at the end of each line.
Example:
var methods = eval(ObjC.classes.UIViewController.$methods);\
for (item in methods) { console.log(item) }\
I want to validate input corresponding to the following grammar snippet:
Declaration:
name = ID "=" brCon=BracketContent
;
BracketContent:
decCon=DecContent (comp+=COMPARATOR content+=DecContent)*
;
DecContent:
(neg=("!"|"not"))? singleContent=VarContent (op+=OPERATOR nextCon+=VarContent)*
;
My validation looks like that:
#Check
def checkNoCycleInHierarchy(Declaration dec) {
if(dec.decCon.singleContent.reference == null) {
return
}
var names = newArrayList
var con = dec.decCon.singleContent
while(con.reference != null) {
con = getThatReference(con).singleContent
if(names.contains(getParentName(con))) {
val errorMsg = "Cycle in hierarchy!"
error(errorMsg,
SQFPackage.eINSTANCE.bracketContent_DecCon,
CYCLE_IN_HIERARCHY)
return
}
names.add(getParentName(con))
}
}
But when I test this validation with a testCaseit returns me an error message:
Expected ERROR 'raven.sqf.CycleInHierarchy' on Declaration at [-1:-1] but got
ERROR (org.eclipse.emf.ecore.impl.EClassImpl#5a7fe64f (name: Declaration) (instanceClassName: null) (abstract: false, interface: false).0) 'Error executing EValidator', offset null, length null
ERROR (org.eclipse.emf.ecore.impl.EClassImpl#5a7fe64f (name: Declaration) (instanceClassName: null) (abstract: false, interface: false).0) 'Error executing EValidator', offset null, length null
I just can't figure out what's wrong with it so I hope that someone of you might have an idea.
Greetings Krzmbrzl
You test utility tells you that the validator did not produce the expected validation error ("CycleInHierarchy").
Instead, the validator produced the error "Error executing EValidator".
Which means an exception has been thrown when your validator was executed.
It turned out it was an internal error...I'm still not exactly sure what went wrong but I have rewritten my validation method and now it works as expected.
Now the method looks like this:
enter code here#Check
def checkNoCycleInHierarchy(Declaration dec) {
if(dec.varContent.reference == null) {
//proceed only if there is a reference
return
}
var content = dec.varContent
var names = newArrayList
while(content.reference != null && !names.contains(getParentName(content))) {
names.add(getParentName(content))
content = content.reference.varContent
if(names.contains(getParentName(content))) {
val errorMsg = "Cycle in hierarchy!"
error(errorMsg,
SQFPackage.eINSTANCE.declaration_BrCon,
CYCLE_IN_HIERARCHY)
return
}
}
}
I have the suspicion that there was a problem with the usage of my "getThatReference" in this case.

What am I doing wrong?
Edit: Upon further investigation I believe the culprit is
EmberWorkouts.WorkoutsRoute = Ember.Route.extend(
model: -> EmberWorkouts.Workout.find()
This doesn't actually return anything. How do I debug from there?
If I replace that with this
EmberWorkouts.WorkoutsRoute = Ember.Route.extend
model: -> [{title: 'hi'}, {title: 'damn'}]
The view actually renders content.
How do I get the model to collect from Rails properly?
Ember Data's interface has changed a little with the current release:
You can clear out the store.js file entirely. Ember Data will automatically set up a data store for you using the REST Adapter (unless you tell it otherwise).
Use model: -> #store.find('workout') instead.
I tested this with your app and it works.
If you haven't read through the Ember Data Guide in the last week or two (it's changed a lot), I would spend a few minutes on it.
The fix for this error (as of ember-data 1.0.0.beta.6) for me was to make sure that the JSON returned from the server included an "id" field for each model, BUT not to explicitly declare the id when setting up the Ember DS.Model.
jbuilder template:
json.scans do
json.array! #scans do |scan|
json.id scan.id # This prop has to be there
json.name scan.name
end
end
Ember model:
EmberApp.Scan = DS.Model.extend(
// Don't include the id prop here
name: DS.attr("string")
)
Code:
public static function selectlogin($sq)
{
$db_handler = self::handler();
$res = $db_handler->query($sq);
foreach ($res as $row)
{
$_SESSION['admin_id'] = $row['id'];
}
return $_SESSION['admin_id'];
}
Error Message
Warning: Invalid argument supplied for foreach()
Can anybody fix this?
I am *not aware of the library that you are using, but before the foreach, you have to use same kind of equivalent of mysql_fetch_array() to convert the SQL Result Resource into an array which you can than work on. The reason for the error is because $res contains a Result Resource, not the result itself.
Yep! ... Your $res is a falsy value. NULL or FALSE.
if ($res)
{
for ($res as $row)
{
$_SESSION['admin_id'] = $row['id'];
}
return $_SESSION['admin_id'];
}
can you try this
if (is_array($res))
{
foreach ($res as $row)
{
// store
}
}
We check if array is not empty. and this way its cleaner.
PDO::query() returns a PDOStatement object, or FALSE on failure
var_dump($res); what is output?
