99封情书 提交于 2021-01-28 01:57:18

The current camel version is 2.22.0, according to the camel documentation this supports JSON schema v4, v6, v7 and v2019-09 using the NetworkNT JSON Schema library.

How can I implement dynamic validation in activerecord

问题 What is the best way to adjust your validation of a model based on a parameter or action? Say I am entering a lead into a system, so all that is required is basic contact info. But then later I may enter a new contract for that user at which point I need more detailed information. So I may need phone number when just entering a lead but once they are entering into a contract I might need their birthdate and alternate phone number. I considered using a state machine but the user could actually

问题 I am trying to create a dependent list as described and answered (with a script) here. I would like to achieve that if selecting a certain value (e.g. "First") from a cell in column 1, then the drop-down options from the next cell in the same row should offer a range of values from the column in a different sheet with the same heading as the value in the first - left - cell (i.e. the first sheet is called "Selector" - in which there are dropdowns, in the second sheet called "KAT" I have the

Choose random validation data set

纵然是瞬间 提交于 2021-01-27 13:09:05
问题 Given a numpy array consisting of data which has been generated for ongoing time from a simulation. Based on this I'm using tensorflow and keras to train a neural network and my question refers to this line of code in my model: model.fit(X1, Y1, epochs=1000, batch_size=100, verbose=1, shuffle=True, validation_split=0.2) After having read in the documentation of Keras I found out that the validation data set (in this case 20% of the original data) is sliced from the end. As Im generating data

Are supplementary characters allowed in XML names?

て烟熏妆下的殇ゞ 提交于 2021-01-27 12:48:07
问题 According to the specification the characters [#x10000-#xEFFFF] are legal in XML names. However, the W3 validator says that this XML is not well-formed: <?xml version="1.0"?> <𐐀>value</𐐀> (the name of the attribute is a Unicode character #x10400). Some browsers, like Firefox, also complain about it (Chrome displays XML, IE shows a blank page). Is it an error in tools or the XML is really not well-formed? 回答1: Is it an error in tools or the XML is really not well-formed? It's well formed in

孤街醉人 提交于 2021-01-27 08:33:16
问题 We are trying to build an incoming request validation platform using HAProxy+Lua. Our use-case is to create a LUA scripts that will essentially make a socket call to a Validation API, and based on the response from Validation API we want to redirect the request to a backend API, and if the validation fails we would want to return the request right from the LUA script. For example, for 200 response we would want to redirect the request to backend api, and for 404 we would want to return the
