Hyperledger Composer Rest Server connection with Cloudant I'm trying to use Cloudant NoSQL DB as a persistent data source for my blockchain identities in my composer rest server. I have the composer-rest server setup in multiuser mode and is using google OAuth for authentication. I have looked at this question (Hyperledger Composer Rest Server connection with Cloudant NoSQL DB) but I'm still experiencing problems. If I do a composer card list in my terminal I can see the cards in my cloudant database. However, if I do a http get method from my rest server it returns an empty array. I have the COMPOSER_DATSOURCES variable set to {"db": { "name": "db", "connector": "cloudant", "username": "83bcdcfc-327b-xxxxxxxxxxxxx4e0ba4a9-bluemix", "password": "01e6d7xxxxxxxxxxxxxxxxb29adcc85ab35ce9ba", "database": "wallet" } } In cloudant, I have one database called wallet ...

XPATH syntax validator in Python I develop a crawler with many actions. Many xpaths are involving and for this reason I use a json file for storing. Then crawler start running I would like to make a basic syntax check (before xpath usage) on xpaths and raise error for invalid xpaths. for example: xpath1 = '//*[@id="react-root"]/section' xpath2 = '//*[[@id="react-root"]/section' xpath3 = '//*[@id="react-root"]section' from these xpaths only xpath1 is valid is there any module or regex which does this kind of validation? 1 Answer 1 You can compile the xpath strings with lxml.etree.XPath which will raise an exception if the syntax is incorrect: lxml.etree.XPath >>> import lxml.etree >>> lxml.etree.XPath('//*[@id="react-root"]/section') //*[@id="react-root"]/section >>> lxml.etree.XPath('//*...

Exception member class OOP I have met the following concept in the production code: class A { public: class Exception : public std::exception {/* ... */}; //... }; Nobody can give me a clear answer why it is like this. My question is whether this approach is in line with SOLID rules? I think that would be better if this exception class is located outside the class A and is injected while creating the instance of A. Design principles are important, but they aren't followed "because they are design principles". They are followed because they accomplish something. What would injecting the exception object upon construction accomplish? Now the class should manage this objects lifetime. What if an error state is never encountered, and it's never thrown? – StoryTeller Jul 2 at 6:16 ...

Creating React component vs using CSS styling I have created a tab menu using CSS styling that I use in several different spots in my ReactJS app. .tab { overflow: hidden; border: 1px solid #ccc; background-color: #f1f1f1; margin: 0; padding: 0; } .tab button { background-color: inherit; float: left; border: none; outline: none; cursor: pointer; padding: 14px 16px; transition: 0.3s; } .tab button:hover { background-color: #ddd; } .tab button:disabled { background-color: #ccc; cursor: default; } .tabcontent { display: none; padding: 6px 12px; border: 1px solid #ccc; border-top:none; } This is in a index.css file that sits with all my .js files. Within my React code I use it like this, as an example: index.css .js <table><tbody> <tr className="tab"><td> <button onClick={() => this.openTab(0)}>Tab 1</button> <button onClick={() => this.op...

Get the field that is going to be edited in kendo beforeedit event I have a dependent column that needs to be editable based on value of the first cell. How can do this using the beforeedit event of kendo grid. I wish to avoid closing the cell in edit event of kendo grid. Below is a sample https://dojo.telerik.com/enodEwub 1 Answer 1 In order to achieve this when "Inline" edit mode is used you can use the Grid's cancelRow() method. $("#grid").kendoGrid({ //.... edit: onEdit }); function onEdit(e) { //your custom logic $('#grid').data("kendoGrid").cancelRow(); } Hope that helps! grid seems to break. dojo.telerik.com/enodEwub – Jose Tuttu Jul 2 at 11:40 Also, cancelRow is sup...

ECharts: Disable default click action on legends I'm trying to use ECharts to render a simple doughnut chart which I've been able to do. I've noticed by default that the legend will hide the data item on the chart if it is clicked. I want the user to be able to select the legend to do something (fire an event) which I can do using the events available (https://ecomfe.github.io/echarts-doc/public/en/api.html#events.legendselected) however I want to prevent the default behaviour of hiding/showing the data item on the chart. In the documentation there is mention of a property on the legend called selectedMode (https://ecomfe.github.io/echarts-doc/public/en/option.html#legend.selectedMode), which prevents the toggling of the series, but it also stops the legend from being selectable entirely. I've also tried returning false on the events fired for legendselected and legendunselected but to no success. Has anyone found a way of stopping this behaviour? I'd appreciate any...

<activity> does not have valid android:name [duplicate] This question already has an answer here: I have trouble with the INSTALL_PARSE_FAILED_MANIFEST_MALFORMED error where I looked into logcat where the following was my error: W/PackageParser: /data/app/vmdl-1226238136.tmp (at Binary XML file line #27): does not have valid android:name I looked into my manifest code and after searching through a lot of forums (adding . before my activity name, adding big letters and etcetera) it does not work.

R Extract values from data frame with vectors I hope my question is not a duplicate, but I really couldn't find what I need. I dived in dplyr and even did the data.table course from DataCamp, but I can't fix it. Maybe overlooking something? I have this df: set.seed(1964) df<-data.frame(id = c( "XEY", "NZH", "DYE", "JNF", "LHH", "WNB"), q_1 = sample(5,6, replace = TRUE), q_2 = sample(5,6, replace = TRUE), q_3 = sample(5,6, replace = TRUE), q_4 = sample(5,6, replace = TRUE), q_5 = sample(5,6, replace = TRUE)) So my df looks like this: Next I have two vectors with id's (row-indicators) and q's (question numbers) like these: id <- c("XEY", "DYE", "JNF", "DYE", "XEY", "LHH", "WNB", "JNF" ) question <- c("val_1", "val_1","val_3","val_3"...

The activity is not responding I have been working on developing an application which needed login and signup screen. My register activity is not working properly. The application is unable to take user from the start screen to the register activity, first the error arose of absence of intent filter then I included the intent filter in the manifest file but it seems like my app is ignoring the register activity. I am attaching both manifest file and the activity code please have a look.
