Camel-case

camel(name, firstCharUpper)

Convert a database field or an upper-case parameter containing underscores (_) to the camel case format, i.e. lowercase and the underscore remove and next character to uppercase.

Example:

var x = utils.camel("ABC_DEF",false); -> x = "abcDef"

var x = utils.camel("ABC_DEF",true); -> x = "AbcDef"

Snake-case

camelToSnake(name, toUpperCase)

It is the opposite function of the camel-case function: it converts a camel case string to snake case, i.e a string expressed in lowercase with an underscore (_) separating each uppercase character in the original string.

Example:

var x = utils.camelToSnake("abcDEF",false); -> x = "abc_d_e_f"

var x = utils.camelToSnake("abcDEF",true); -> x = "ABC_D_E_F"

Uncamel

uncamel(attributeName)

It converts an attribute name to a field name, according to Java convention.

Example:

var x = utils.uncamel("abcD1",true); -> x = "ABC_D1"

Enqueuing server-side js actions

enqueueAction(queueName, actionId, params, priority, processWaitTime, logExecution);

The arguments are:

  • queueName– optional: queue name; if not specified, the process will be enqueued in the DEFAULT queue

  • actionId– server-side javascript action identifier to execute

  • param– javascript object containing parameters to pass to the action

  • priority– optional; if specified, processes within the same queue will be sorted according to the priority rathe than to the enqueuing time

  • processWaitTime– optional; if specified, the process will not be started before that time, expressed in seconds

  • logExecution– true to log in the predefined table LOG60_LOGS the execution of the process

Note: the javascript object specified through the "param" can accept an optional attribute named "queueTimeout": when the action execution time overpasses that value, (expressed in minutes), the element is marked as "timeout" in the queue and the queue is then unlocked, in order to allow extracting new elements from it. Note that the current action is still under execution and this could create drawbacks in case of actions which should be executed sequentially, since the work on the same set of data,by writing them.

There is a variant of the method described above, having one more argument:

enqueueActionWithNote(queueName, actionId, params, priority, processWaitTime, logExecution, note);

where note is a string value which will be saved in the NOTE field of the CON77_QUEUES table. This field can be helpful to carry out custom logic on the enqueued elements, for instance to execute statistics about the amount of data not processed yet.

Enqueuing multiple elements in queue, starting from a SQL query

It is possible to speed up the enqueuing process of a large amount of elements, starting from a SQL query whose result (a list of records) represents the data to pass forward to each element in the queue. For each record read from the SQL query, an element is enqueued in the specified queue: such an element would receive in input the current record.

This can improve the enqueuing process of about 40%.

Syntax

utils.enqueueActionsFromSqlQuery(
  String queueName,String payload,Long actionId,
  Long datasourceId,String sqlQuery,Object[] params
);
ArgumentDescription

queueName

name of the queue where all elements will be inserted

payload

optional payload to pass forward to each element

actionId

to enqueued action id

datasourceId

optional datasource id where the SQL query will be executed

sqlQuery

SQL query to execute: for each record, an element will be enqueued and the record would represent the input data

params

optional list of parameters to pass to the SQL Query (where they are referred always as ?); set to [] in case of no parameters.

  • cmd – shell command to execute

  • priority– optional; if specified, processes within the same queue will be sorted according to the priority rathe than to the enqueing time

  • processWaitTime – optional; if specified, the process will not be started before that time, expressed in seconds

  • logExecution– true to log in LOG60_LOGS the execution of the process

Create a link to access the web app from an email or other external media

In case you need to create a dynamic link which allows you to access a Platform web application, linked to a specific username, you can use this method:

var token = utils.createAllowedLink(
  expirationDays, // expirationDays = 0 for no expiration
  maxTimes
);

The required arguments are:

  • expirationDays – optional: it defines the validity of this link, expressed as number of days; if not specified, the link is always valid

  • maxTimes – optional: it defines the validity of this link, expressed as the number of times it can be used; after reaching this number, the link cannot be used anymore; if not specified, the link is always valid.

This method returns a token, which is a dynamically generated text you can include when logging on the web app.

Note: the link can become invalid either if it reaches the expiration time or when it has been used the max number of times.

Important note: it is strongly recommended to always specify at least one of the 2 arguments, so that the link will expire: this will make your Platform web application more secure.

Create a link to access the web app from an email or other external media with additional data

In case you need to create a dynamic link which allows you to access a Platform web application, linked to a specific username and you also need to pass forward additional data, you can use this method:

var token = utils.createAllowedLinkWithRtk(
  expirationDays, // expirationDays = 0 for no expiration
  maxTimes,
  rtk
);

The required arguments are:

  • expirationDays – optional: it defines the validity of this link, expressed as number of days; if not specified, the link is always valid

  • maxTimes – optional: it defines the validity of this link, expressed as the number of times it can be used; after reaching this number, the link cannot be used anymore; if not specified, the link is always valid

  • rtk - additional data to include, expressed as a String. You can get this content through the getEncodedRtk.

This method returns a token, which is a dynamically generated text you can include when logging on the web app.

Note: the link can become invalid either if it reaches the expiration time or when it has been used the max number of times.

Important note: it is strongly recommended to always specify at least one of the 2 first arguments, so that the link will expire: this will make your Platform web application more secure.

Enconding data to send externally

In case you need to encode data which you need to send outside, for instance in a link, you can use this method:

var token = utils.getEncodedRtk(String... data);

The required arguments are:

  • data – data list to encode

This method returns a String object, that can be used for instance in the method createAllowedLinkWithRtk.

Note: this method will NOT encrypt data: it only obfuscates data, by not makes it visible in plain text.

If you need more protection and encrypt data, use the method getEncToken instead.

Encrypting data to send externally

In case you need to encrypt data which you need to send outside, for instance in a link, you can use this method:

var token = utils.getEncToken(String... data);

The required arguments are:

This method returns a String object, that can be used for instance in the method createAllowedLinkWithRtk.

Decrypting data received from the outside

In case you need to decrypt data which has been previously encripted and you need to decode it, you can use this method:

var data = utils.decodeEncToken(String token);

The required arguments are:

  • token – encrypted content, expressed as a String received in input

This method returns a String object. Important note: use this method only in combination with getEncToken, since it can only decrypt content previously decripted by it.

Convert a text to an hash key (md5)

MD5 is an hash function you can use to convert a text to a text-based key; multiple invocations to the function with the same input always provide the same result, but the hash function does not provide a unique value: different texts could return the same hash key. This is helpful to check out on the database table the existence of a specific record, starting from its md5 representation.

var md5Text= utils.md5(String text);

Details

Argument

Description

text

text to convert to an hash key

md5Text

the MD5 hash key corresponding to the input text

Setting a value in a value object to save from a server-side js action

In case you are saving data from a grid or form, using the standard Platform saving system (form Save button on the UI), you can inject new attributes or change attribute values just before saving data on the server. Using the "before saving data on insert/update" event, you can link a server-side js action. Here you can execute any kind of business logic and the use calculated data and inject it in the "vo" which is just to be saved, through the following method:

utils.setAttributeValue(String attrName,Object value);

Details

Argument

Description

attrName

attribute name to set in the "vo" Platform is working on to save data

value

value to set for this attribute

Convert a javascript object to a JSON string to work with in an action

In case you need to convert a javascript object to a JSON string within a server-side javascript action, you can use the following method:

var jsonString = utils.stringify(Object obj);

Details

Argument

Description

obj

javascript object to convert

Such a method is helpful in case of a complex object containing java-type objects rather than javascript-type data.

As an alternative, you can use the standard javascript utility function:

var jsonString = JSON.stringify(jsonCarrello,jsonReplacer)

Convert a javascript object to a JSON strings compatible with a database field

In case you need to convert a javascript object to a JSON string you wanna save in to a database field, you have to save it using escape characters, otherwise it would be impossibile to use JSON.parse() later. This is a utility method you can use for that:

var jsonString = utils.stringifyForDatabaseField(Object obj);

Details

Argument

Description

obj

javascript object to convert

Example:

var obj = {
  text: "ABC"
};
var text = utils.stringifyForDatabaseField(obj);
// text is "{ \"text\": \"ABC\" }"
// and it can be saved into a database field and then used to be reconverted to a js object

Invoking a server-side action from another one

When you need to invoke a second server-side js class, starting from a first server-side javascript action and pass forward some input data, you can use one of the following two methods, deferring only for the transaction management:

  • utils.executeActionSameTransaction(Long actionId,Map vo,Map params,Map headers) - the invoked action inherits the same transaction, that is to say, if the first one has written data in the database and does not commit data yet, this data is visibile from the second action as well

  • utils.executeAction(Long actionId,Map vo,Map params,Map headers) - the invoked action creates its own SQL transaction, which is independent from the one owned by the first action; pay attention in such a scenario: you cannot see data written by the first action not committed yet and you cannot update data written by the first action or this would leads to a database lock!

Example:

var actionId = ...
var vo = {
  ...
};
var jsonResult = utils.executeActionSameTransaction(
  actionId,
  vo,
  {}, // params,
  {}  // headers
);

The action invocation is synchronous in both scenarios: the calling action suspends its execution until the called action terminates; moreover, in case of exceptions not managed by the called action, these exceptions will be propagated to the first action , which must be designed to manage them as well.

Setting the company id in a server-side js action if not null

In case the company id has not been set yet, this method allows to set it.
